Ran into this issue, npm i @ionic/app-scripts was the only thing that worked.

I tried this but it didn't work for me and threw errors:

npm --depth 9999 update 
npm rebuild node-sass

I have installed the latest Node.js (which for the moment is 11.11.0 Current), after facing this problem I just did the following:

1. downgrade to recommended version (which for the moment is 10.15.3 LTS)
   • you can get it from NodeJS,
2. deleted node_modules and
3. then reinstall yarn:

     yarn install
     yarn start

After executing these commands everything is working fine for me.

rolling back to node v10.17.0 fixed the problem to me.

You can use nvm to do so:

https://github.com/nvm-sh/nvm

> nvm install 10.17.0
> nvm use 10.17.0
> node -v
10.17.0

Removing node_modules and running npm install fixed those errors for me.

Others say: npm rebuild node-sass or npm audit fix might help.

None of the above worked in my case.

I was using Node 15.5.0, but this version is not compatible with node-sass. So, I deleted current Node (Add/remove programs in Windows), and installed 14.15.3 version.

Try to delete node_modules and do npm install again after you finish node installation.

Inside package.json convert node-sass version to :

"node-sass": "^4.0.0"

In my case the issue was when I installation of the node latest version i.e; 10.6.0. The same error was showing and with reference to @Quinn Uninstalled that version and installed the 8.11.3 LTS version. Now working Fine :)

I got this error, with angular 7, what helped me is, From the windows power shell I run the command:

npm install --global --production windows-build-tools

then again I reopen my VS Code, on it's terminal I run the same command npm uninstall node-sass and npm install node-sass

npm uninstall node-sass && npm install node-sass is the better way to fix

for visual studio 2019 need change MSBuild path

npm config set msvs_version 2017

npm config set msbuild_path "C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\MSBuild\Current\Bin\MSBuild.exe"

npm rebuild node-sass

Working for me only after installing Python 2.7.x (not 3.x) and then npm uninstall node-sass && npm install node-sass like @Quinn Comendant said.

In my case, it was related to the node version.

My project was using 12.18.3 but I was on 14.5.0

So npm rebuild node-sass didn't solve the issue on the wrong node version(14.5.0).

I switched to the correct version(12.18.3) so it worked.

The link from the stack trace below helped me in resolving this issue.

Module build failed: Error: Node Sass does not yet support your current environment: Windows 64-bit with Unsupported runtime (64)
For more information on which environments are supported please see:
https://github.com/sass/node-sass/releases/tag/v4.7.2

This link(https://github.com/sass/node-sass/releases/tag/v4.7.2) clearly shows node versions which are supported.

    OS      Architecture    Node
    Windows x86 & x64       0.10, 0.12, 1, 2, 3, 4, 5, 6, 7, 8, 9
    ...     ...             ...    

After downgrading the node version to 8.11.1, executed npm install again. Got the following message.

Node Sass could not find a binding for your current environment: Windows 64-bit with Node.js 8.x

Found bindings for the following environments:
  - Windows 64-bit with Unsupported runtime (64)

This usually happens because your environment has changed since running `npm install`.
Run `npm rebuild node-sass --force` to build the binding for your current environment.

Finally,ran npm rebuild node-sass --force as instructed and all started working

Here are node and node-sass compatible versions list.

NodeJS  Supported node-sass version *
Node    15        5.0+   
Node    14        4.14+ 
Node    13        4.13+, < 5.0   
Node    12        4.12+  
Node    11        4.10+, < 5.0   
Node    10        4.9+   
Node     8        4.5.3+, < 5.0  
Node  <  8   <    5.0     < 57

If issue exists, upgrade or downgrade versions.

None of the above worked for me. I completely removed and than re-installed and it solved the issue.

To delete existing:

npm uninstall --save-dev node-sass 

Then to re-install:

npm install --save-dev node-sass

For me, this problem was solved by uninstalling the latest version of node and replacing it with the LTS version.

I've tried all the suggestions here. Rebuilding, uninstalling and reinstalling, etc...

Switching from node 14 to node 10 is the only way that worked for me. I know it may not be the best solution but in my case it is ok.

Try this:

npm --depth 9999 update
npm rebuild node-sass

I had the same problem and I solved it as follows:

1. check the node-sass version used in the current project

2. go to node-sass release: "https://github.com/sass/node-sass/releases/tag/v@.@.@" (put your node-sass version here)

3. check the Supported Environment table and see if your Node version exist in it

4. if it is not, downgrade your node version to the latest version existing in the table

I know it's not the perfect solution but I didn't find anything else in my case.

Are you using Git-Bash in Windows? I was getting the same error until I tried PowerShell and magically this error disappeared.

Check the Node Sass release notes for the version of node-sass you have, to see which version of node is required. If the version of node is wrong, you must downgrade node, or upgrade node-sass, until you have a compatible pair. If the node version is supported, you may just need to run npm rebuild node-sass.If that doesn't work, you can npm uninstall node-sass or npm install node-sass

I got this error when I updated node using NVM. to remove this run; npm rebuild node-sass

Commands npm uninstall node-sass && npm install node-sass didn't help me, but after installing Python 2.7 and Visual C++ Build Tools I deleted node_modules folder, opened CMD from Administrator and ran npm install --msvs_version=2015. And it installed successfully!

This comment and this link can help too.
