I\'m trying to install LESS on my machine and have installed node already. However, when I enter \"node install -g less\" I get the following error and am not sure what to d
This will definitely help. Answer by npm itself. https://docs.npmjs.com/getting-started/fixing-npm-permissions
Below is extracted from the URL for your convenience.
Option 1: Change the permission to npm's default directory
Find the path to npm's directory:
npm config get prefix
For many systems, this will be /usr/local.
WARNING: If the displayed path is just /usr, switch to Option 2 or you will mess up your permissions.
Change the owner of npm's directories to the name of the current user (your username!):
sudo chown -R $(whoami) $(npm config get prefix)/{lib/node_modules,bin,share}
This changes the permissions of the sub-folders used by npm and some other tools (lib/node_modules, bin, and share).
Option 2: Change npm's default directory to another directory
Make a directory for global installations:
mkdir ~/.npm-global
Configure npm to use the new directory path:
npm config set prefix '~/.npm-global'
Open or create a ~/.profile file and add this line:
export PATH=~/.npm-global/bin:$PATH
Back on the command line, update your system variables:
source ~/.profile
Test: Download a package globally without using sudo.
`npm install -g jshint`
Instead of steps 2-4, you can use the corresponding ENV variable (e.g. if you don't want to modify ~/.profile):
NPM_CONFIG_PREFIX=~/.npm-global
Option 3: Use a package manager that takes care of this for you
If you're doing a fresh install of Node on Mac OS, you can avoid this problem altogether by using the Homebrew package manager. Homebrew sets things up out of the box with the correct permissions.
brew install node
