[node.js] Node Sass couldn't find a binding for your current environment

I am having issues building an app because node-sass keeps failing with the error.

ERROR in Missing binding /Users/warren/Sites/random-docs/my-cms/node_modules/node-sass/vendor/darwin-x64-11/binding.node
Node Sass could not find a binding for your current environment: OS X 64-bit with Node 0.10.x

I have tried running

npm rebuild node-sass

which says

Binary is fine; exiting.

When running node -v I get v6.2.2

Which is different to what the sass error says "Node 0.10.x". I can't figure out why it is getting the wrong version. I have also tried removing the node_modules folder and running npm update or npm install, both of which did not resolve the issue. Any ideas?

This question is related to node.js npm

The answer is

Check your system: Does your system has 2 different Node.js installation?

If you install node from nodejs, the default installation directory is C:\Program Files\nodejs I had the node version 6.xx installed here.

Check your VS External web tools directory C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Web\External I had the node version 5.xx installed there.

One work around is :

  • Make backup of C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Web\External directory.
  • Copy C:\Program Files\nodejs directory content and
  • paste into C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Web\External Directory.
  • Delete node_modules directory from your solution.
  • Re run the project. If you get error message re run the project second time.

If that does not work

  • Delete node_modules directory from your solution.

NOTE: $ is the command prompt

$  npm install 
$ npm run build:dev

Rerun the project.

Please write below command on Root Folder.

npm rebuild node-sass

100% works...

For people that switched to nvm from system node, if you haven't removed the ~/.npm and ~/.node-gyp folder this problem can arise since perhaps the node version within ~/.node-gyp could be different.

In any case those folders should be removed.

I had the same problem in a Windows environment, receiving the following error:

Error: Missing binding C:\Development{ProjectName}\node_modules\node-sass\vendor\win32-ia32-47\binding.node
Node Sass could not find a binding for your current environment: Windows 32-bit with Node.js 5.x
Found bindings for the following environments:
   - Windows 64-bit with Node.js 6.x

None of the npm commands listed in the other answers here (npm install, npm rebuild node-sass, etc.) worked.

Instead, I had to download the missing binding and place it in the appropriate destination folder.

The bindings can be found on git. Match the file with the folder name identified after /node_modules/node-sass/vendor/ in your error message ('darwin-x64-11' in your case, so you'd want the darwin-x64-11_binding.node file).

Create the missing folder in your project (/node_modules/node-sass/vendor/darwin-x64-11), copy the .node file to the new directory, and rename it to binding.node.

Node-sass release URL: https://github.com/sass/node-sass/releases

node-sass node module uses darwin binary file which is dependent on the version of node. This issue occurs when the binary file is not downloaded or wrong binary file is downloaded.

Node sass error

Reinstall node modules will download expected binary of node-sass:-

For Mac users:

rm -rf node_modules
npm cache clean --force
npm i
npm rebuild node-sass --force

For Windows users:

rmdir node_modules
npm cache clean --force
npm i
npm rebuild node-sass --force

but for some users, you need to check your node version's compatibility with node-sass version. Make it compatible using below table and run above commands again to fix this issue.

Node JS compatible node-sass version

If issue is still not fixed, check node-sass supported environment's list:- https://github.com/sass/node-sass/releases/

I am able to fix issue with npm install --global --production windows-build-tools

npm install --msvs_version=2015

"devDependencies": { "babel-core": "^6.26.0", "babel-loader": "^7.1.4", "babel-plugin-transform-decorators-legacy": "^1.3.5", "babel-preset-env": "^1.6.1", "babel-preset-react": "^6.24.1", "babel-preset-stage-2": "^6.24.1", "css-loader": "^0.28.11", "mini-css-extract-plugin": "^0.4.0", "node-sass": "^4.11.0", "sass-loader": "^6.0.7", "webpack": "^4.4.1", "webpack-cli": "3.1.0", "webpack-dev-server": "^3.1.1" }

node-sass runs an install script to download the required binary. If there are no environment variables, .npmrc variables or process arguments set then the binary is determined by using the current process platform, architecture and Node ABI version. Therefore, if you run node install in one application and then try to run node-sass in an application with a different platform/architecture/ABI, the binary won't have been downloaded. The solution is to manually download the binary or to fix the binary version using an environment variable (SASS_BINARY_NAME) or a .npmrc variable (sass_binary_name)

You can see the logic for this in the getBinaryPath function in node-sass\lib\extensions.js

I had the same issue. I couldn't find any proper working solution in here, so I found mine:

Inspired by @Rob-Scott solution and other pointing that we could have 2 versions of Node.js installed, I went to C:\Program Files (x86)\nodejs and realized that I had a node.js version installed in addition to the VS default installation.

My solution was quite simple:

  • Go to Tools > Options > Projects & solutions > Web package management > External web tools
  • Click on add an entry (most left of the top-right block of buttons)
  • Enter C:\Program Files (x86)\nodejs, validate by pressing enter
  • Bring it at the top of the list
  • Enjoy

Probably Node.js is not set well in the PATH variable, but this is my working very quick solution, my 2 cents :)

Windows 10 This was a fun one for me... In order to resolve it I had to do all of the following.. 1.) Apparently node-sass isn't supported by some of the more recent versions of Node.js so I had to Uninstall Node-v 12.14.1, and delete the nodejs directory in C:/Program Files. 2.) Reinstall a earlier version of Node (for me 10.16.2 worked). NOTE: I had initially downloaded the x86 version so if your System is x64 download the x64 verison... 3.) From here I had to delete my entire project and re-clone it. After this things ran fine.

Install Xcode if you are on a mac.

I tried all the above, nothing worked, I was trying to match the node version to the node-sass version when I decided to go to the official node.js website, download the latest node version(currently v14 and I was on v12) and install it. This fixed my issue at last! It's possible that your node-sass version is ahead of your node.js version.

The problem for me was that the Task Runner Explorer was targeting the solution of my project. When I changed to the project itself using the drop-down list, next to the Task Runner Explorer refresh button, it showed the relevant tasks.

For Mac:

  2. -/usr/local/lib/node-sass
  3. -right click and renamed: should still the same node-sass
  4. -then run: npm install node-sass -g

that fixed.

Worked for me:

Just delete the node-sass folder and run npm install.

This happens when in your workstation you run an update of Node.js and you are using node-sass globally.

So you should uninstall node-sass globally

npm uninstall -g node-sass

And then you have to install it globally, again

npm install -g node-sass

I had to first choose the new default node version nvm use *** or nvm install *** and then remove all in node_modules in the project and npm i again.

Answer by @core114 suggesting Uninstalling & installing sass package again works fine for manual process but for automated deployment/CI/CD you need more generic approach. What worked for me is for Continuos deployment of different environment is :

  1. removing old node_modules using rimraf before deployment

    rimraf node_modules

  2. Updating sass package in npm package.json & committing to source control.

For next deployment it will automatically refresh sass for all environment.

I had a similar problem and the reason was that there were two versions of Node installed in my machine: one "global" and another one at the project level. Sass will build correctly only if the Gulp build is running under Node.js 4.x version, so make sure you upgrade the version of Node you are using.

PS: If you completely remove the node_modules folder in your project and re-build from scratch, npm will download the correct dependencies for your current system & node version.

  1. Delete node_modules folder.
  2. Install dependencies again. (npm i)

* Docker related answer here *

Answer for if you are seeing this problem, or something similar, and are using Docker.

Cause: When copying over the current file structure to inside the Docker container, you may be copying over node modules from one OS system to another (e.g. a Mac to Linux container).


Add a .dockerignore, and inside add:


This will cause an npm install to install the bindings for the docker environment, rather than your local machine environment.

in some cases you need to uninstall and install node-sass library. Try:

npm uninstall --save node-sass


npm install --save node-sass

look at this its work for me, Stack link here

I fixed this by changing JAVA_HOME from x86 to x64. Maven was running on x86 but node was using x64. Remove /node and /node_modules and build again.

Just run the comment thats it.

npm rebuild node-sass

enjoy your coding...

npm rebuild node-sass --force

Or, if you are using node-sass within a container:

docker exec <container-id> npm rebuild node-sass --force

This error occurs when node-sass does not have the correct binding for the current operating system.

If you use Docker, this error usually happens when you add node_modules directly to the container filesystem in your Dockerfile (or mount them using a Docker volume).

The container architecture is probably different than your current operating system. For example, I installed node-sass on macOS but my container runs Ubuntu.

If you force node-sass to rebuild from within the container, node-sass will download the correct bindings for the container operating system.

See my repro case to learn more.

This is something that may not happen to anyone else, but in my case, this error appeared when I decided to restart my project (to follow a different vue.js tutorial).

The steps that created my problem was:

# move my existing project
mv project-name project-name-old
# create a new project
vue create project-name
# run server
npm run server

The problem was that my previous server was still running on a different terminal tab. On localhost:8080, the page that was still showing was the old project.

All I had to do was shut down the old server in the terminal and execute "npm run serve" again (or view localhost:8081).

Just in case this confounds someone else for half an hour, or for laughs and giggles.

When building a docker image and attempting to run it locally I ran into this same issue. You need to add a .dockerignore file with the following: .DS_Store .git .gitignore .idea log/* target tmp node_modules client/node_modules spec/internal/public/assets public/assets

If your terminal/command prompt says:

Node Sass could not find a binding 
for your current environment: 
OS X 64-bit with Node 0.10.x

and you have tried the following commands such as:

npm cache clean --force 
rm -rf node modules 
npm install 
npm rebuild node-sass 
npm rebuild node-sass

& still NOTHING works..

Just run this in the terminal manually:

node node_modules/node-sass/scripts/install.js

now run

npm start or yarn start

Please also remember to rename the xxx.node file ( in my case win32-x64-51) to binding.node and paste in the xxx folder ( in my case win32-x64-51),

A similar error I encountered with Visual Studio 2015 Community Edition while having created an AspNetCore app was:

Node Sass could not find a binding for your current environment: Windows 32-bit with Node.js 5.x
Found bindings for the following environments:
  - Windows 64-bit with Node.js 6.x
This usually happens because your environment has changed since running `npm install`.
Run `npm rebuild node-sass` to build the binding for your current environment.

    at Object.<anonymous> ([..]\node_modules\node-sass\lib\index.js:14:35)
    at Module._compile (module.js:397:26)

    at Object.<anonymous> ([..]\node_modules\gulp-sass\index.js:187:21)
    at Module._compile (module.js:397:26)

You can see the from the error above that the cause was from a version mismatch on the bindings for nodejs.

Node Sass could not find a binding for your current environment: Windows 32-bit with Node.js 5.x

Found bindings for the following environments: - Windows 64-bit with Node.js 6.x

The solution I found was to

  • Install the nodejs windows version,
  • Add path for node js (C:\Program Files\nodejs) in External Web Tools (see Rob Scott's answer),
  • Move nodejs path above $(PATH).

The post dependencies for node-sass is not getting installed without the package.json inside node-sass

Running it manually solved for me

node node_modules/node-sass/scripts/install.js 

credit: link

For me it was the maven-war-plugin that applied filters to the files and corrupted the woff files.


Remove <filtering>true</filtering>

Or if you need filtering you can do something like this:


None of the install/rebuild solutions resolved the issue for me (using gulp).

Here is how I resolved it:

1) Download the missing binding file from the repository.

2) Rename the file binding.node.

3) Create node_modules/node-sass/vendor/darwin-x64-11 (path from error message) directory if it doesn't exist.

4) Add the binding file to node_modules/node-sass/vendor/darwin-x64-11

For my particular case none of the above answers worked. So what it worked:

rm -rf node_modules 
rm -rf /tmp/* 
rm -rf /root/.npm/node-sass 
npm uninstall --save node-sass 
npm cache clean --force 

npm cache verify to check that nothing is left in the cache

npm install

Altough I haven't tried to reproduce the sequence it was a combination of the above that worked. In addition you may also try:

npm install --save node-sass or npm install node-sass -g

npm rebuild node-sass
npm install bindings

Open Visual Studio 2017
Go to Tools -> Options…
Go to Projects and Solutions -> Web Package Management
Move $(PATH) to the top of that list and close that window.
Restart Visual Studio.
This worked in my case, because my node version is 11.x

  1. Create a new directory in node_modules/node-sass/vendor/linux-x64-46/ .
  2. the download fil from https://github.com/sass/node-sass/releases
    (linux-x64-59_binding.node) based upon your version.
  3. paste it in node_modules/node-sass/vendor/linux-x64-46/ rename it to binding.node

I have tried all methods I've found.

I have noticed some strange behavior of that folder. When I was trying to "cd" to 'node_sass' folder from VS terminal, it told that "Folder was not found", but was seen in Finder.

chmod from VS terminal haven't find folder even with 'sudo' command.

I have chmod-ed from native MacOs terminal and just after have rebuild with node.

I had this issue when upgrading from VS 2017 Professional to Enterprise

  1. Close VS
  2. Delete node_modules
  3. Open VS
  4. Right click package.json and select 'restore packages'

I had the same problem with Node v7.4.0 Current (Latest Features).

Did some reading here and downgraded Node to v6.9.4 LTS and after running npm rebuild node-sass it downloaded the binary and everything started working.

Downloading binary from https://github.com/sass/node-sass/releases/download/v3.13.1/win32-x64-48_binding.node
Download complete .] - :
Binary saved to D:\xxx\xxx-xxx\node_modules\node-sass\vendor\win32-x64-48\binding.node
Caching binary to C:\Users\user\AppData\Roaming\npm-cache\node-sass\3.13.1\win32-x64-48_binding.node`

This usually happens because the environment has changed since running npm install. Running npm rebuild node-sass builds the binding for the current environment.

For me, when i ran npm install it audited the installed packages and showed "found 1 high severity vulnerability" and by running

npm audit fix

did the trick. Posting if it helps someone.

Update: Sharing my error log:

ERROR in ./src/styles.scss (./node_modules/@angular-devkit/build-angular/src/angular-cli-files/plugins/raw-css-loader.js!./node_modules/postcss-loader/src??embedded!./node_modules/sass-loader/lib/loader.js??ref--14-3!./src/styles.scss)

This usually happens because your environment has changed since running `npm install`.

It did ask me to

Run `npm rebuild node-sass` to download the binding for your current environment.

remove the /node-modules folder and install it again or run the gradle task deploy after it removed


It solves your problem.

For Visual Studio 2015/2017, Right Click on your package.json and Click on Restore Packages.

This will make sure that the npm from the Visual Studio Tools External Tools is run and the binding will be rebuild based on that.

Note I'm using VS 2015, 64-bit Windows 7.

Also works for VS 2017 and VS 2019 (from replies to this post)

Task Runner Explorer can't load tasks

For VS 2015

  • Go to: Tools > Options > Projects and Solutions > External Web Tools

For VS 2017(.3)

  • Tools > Options > Projects and Solutions > Web Package Management > External Web Tools (per @nothrow)

In VS 2017 & 2019, you also need to put $(PATH) above $(VSINSTALLERDIR)\Web\External

  • Reorder so that $(PATH) is above $(DevEnvDir)\Extensions\Microsoft\Web Tools\External

Deleting node_modules and running npm install and then npm rebuild node-sass did nothing.

Just execute: ? npm rebuild node-sass --force

If the above for some reason didn't work out for you, try this:
  1. Delete node-sass folder under node_modules
  2. npm install

In my case it also couldn't find Python.

Following procedure solved the issue (Windows):

npm rebuild node-sass --force
-- cannot find python.exe, if you have Python installed, add it to your path:
set PYTHON=C:\Python27\Python.exe
-- else: download python "Windows x86-64-MSI" installer from https://www.python.org/downloads/release/python-2714/
-- install python
-- at installation start check: add env variable to path
-- after successfull installation:
npm rebuild node-sass --force
-- finished successfully

This worked for me: yarn add --force [email protected] or yarn add --force node-sass

Try to add suffix --force

npm rebuild node-sass --force

I had the same problem

There is an error in your gulpfile:
Error: Missing binding E:\allapp\badshaindiancuisine\node_module\node-sass\vendor\win32-x64-46\binding.node
Node Sass could not find a binding for your current environment:Windows 64-bit with Node.js 4.x

Found bindings for the following environment:
    - OS X 64-bit with Node.js 4.x

How to solve my problem

By going into project folder and then execute:

npm rebuild node-sass

Run the following commands, it works fine for me.

npm install node-sass -g

npm rebuild node-sass

nvm use 10.16.3

node node_modules/node-sass/scripts/install.js

ng serve --poll=2000

I had the same problem

    throw new Error(errors.missingBinary());

Error: Missing binding /path/to/project/node_modules/node-sass/vendor/linux-x64-47/binding.node
Node Sass could not find a binding for your current environment: Linux 64-bit with Node.js 5.x

Found bindings for the following environments:
  - Linux 64-bit with Node 0.10.x
  - Linux 64-bit with Node.js 5.x

That was because I did npm install using a different nodejs version, try deleting node_modules folder installing and starting

cd your_project
rm -rf node_modules
npm install
npm start or gulp or whatever

If you are using nvm do

nvm use stable // or your favorite version
// remove node_module directory
npm install
npm start or gulp or whatever

This worked for me Deleting node_modules and then restoring packages from IDE and then npm rebuild node-sass

I just run npm rebuild instead of npm rebuild node-sass and issue gone.. I don't know what is the magic behind though.

Check if your version of npm is the same that you project require to

I'm a Windows 8 user, recently updated Node to v8.11.1 and npm to v6.0.0 and faced similar issue. Nothing worked - npm install -g node-sass@latest or deleting the node-sass directory from the project node_modules/ - none of 'em worked for me.

The Laravel Mix was throwing an error to my browser console saying a missing node: win32-x64-57. I don't know whether it's because a slower internet connection or something, the node was missing during the update.

Hence some of the answers directed me to look at the Node-Sass releases, and I found the solution.

  1. Step 1: Check your node-sass version using the command: npm view node-sass version (the {your version} in step 4)
  2. Step 2: Get to Node-Sass Releases
  3. Step 3: Get your release and find the missing node in the assets listed under every release, and download the file
  4. Step 4: Get to your PC's C:\Users\{User}\AppData\Roaming\npm-cache\node-sass\{your version}\ and put the downloaded .node file inside the version folder

And you are done.

In my case the node-sass version was 4.9.0 and the missing node was win32-x64-57_binding.node, so I downloaded the .node file from 4.9.0 release and followed step 4.

On linux ubuntu 20.04 I needed few steps,downgrade node first to apropriate version,remove node_modules,run yarn install and finally run sudo yarn add [email protected] --force.Node version 10.0.0. Only working way for me.

Just refresh your npm cache and:

npm cache clean --force  
npm install

It always works for me in the same case.

UPD: Your problem may also be by reason of absence of a global sasslib.

npm install -g sass
