I'm trying to set up less on phpstorm so I can compile .less files to .css on save. I have installed node.js and the next step (according to this https://www.jetbrains.com/webstorm/help/transpiling-sass-less-and-scss-to-css.html) is running this command in the terminal
npm install -g less
However when I do this I get these errors
? ~ npm install -g less

I'm a complete noob here and not sure what to do next. Any help would be very appreciated!
The answer is
Using sudo is not recommended. It may give you permission issue later. While the above works, I am not a fan of changing folders owned by root to be writable for users, although it may only be an issue with multiple users. To work around that, you could use a group, with 'npm users' but that is also more administrative overhead. See here for the options to deal with permissions from the documentation: https://docs.npmjs.com/getting-started/fixing-npm-permissions
I would go for option 2:
To minimize the chance of permissions errors, you can configure npm to use a different directory. In this example, it will be a hidden directory on your home folder.
Make a directory for global installations:
mkdir ~/.npm-globalConfigure npm to use the new directory path:
npm config set prefix '~/.npm-global'Open or create a ~/.profile file and add this line:
export PATH=~/.npm-global/bin:$PATHBack on the command line, update your system variables:
source ~/.profileTest: Download a package globally without using sudo.
npm install -g jshintIf still show permission error run (mac os):
sudo chown -R $USER ~/.npm-global
This works with the default ubuntu install of:
sudo apt-get install nodejs npm
I recommend nvm if you want more flexibility in managing versions:
https://github.com/creationix/nvm
On MacOS use brew, it should work without sudo out of the box if you're on a recent npm version.
Enjoy :)
Run these commands in a terminal window (note: DON'T replace the $USER part... thats a linux command to get your user!):
sudo chown -R $USER ~/.npm
sudo chown -R $USER /usr/lib/node_modules
sudo chown -R $USER /usr/local/lib/node_modules
In linux make sure getting all authority with:
sudo su
Reinstall node and npm with Node Version Manger (as per written in npm documentation) to avoid permission errors:
In OSX:
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.8/install.sh | bash
or follow this article:
http://dev.topheman.com/install-nvm-with-homebrew-to-use-multiple-versions-of-node-and-iojs-easily/
Windows users should install nvm-windows. For further help how to install nvm refer the nvm readme.
Then choose for example:
nvm install 8.0.0
nvm use 8.0
Now you can give another try:
npm install -g less
I have tried all the suggested solutions but nothing worked.
I am using macOS Catalina 10.15.3
Go to /usr/local/
Select bin folder > Get Info
Add your user to Sharing & Permissions.
Read & Write Permissions.
And go to terminal and run npm install -g @ionic/cli
It has helped me.
Another option is to download and install a new version using an installer.
Mac OS X Answer
You don't have write access to the node_modules directory
npm WARN checkPermissions Missing write access to /usr/local/lib/node_modules
Add your User to the directory with write access
Open folder containing node_modules
open /usr/local/lib/
- Do a cmd+I on the node_modules folder to open the permission dialog
- Add your user to have read and write access in the sharing and permissions section
sudo chown -R $USER /usr/local/lib/node_modules This command will work
Use sudo -i to switch to $root, then execute npm install -g xxxx
For my mac environment
sudo chown -R $USER /usr/local/lib/node_modules
solve the issue
