Ammon’s Node/NPM guide

Mac

Installing node with the installer on a MAC is not recommended. It will cause permission errors with globally installed packages and the need to run the SUDO command. A student with the habit of running SUDO on a command to get it to work will cause many issues.

Curriculum uses Homebrew to install Node on MAC, which is recommended.

If there are MAC Node/NPM permission issues, here is the easiest fix: source

mkdir ~/.npm-global
npm config set prefix '~/.npm-global'

add to ~/.bash_profile

export PATH=~/.npm-global/bin:$PATH

There might still be errors installing packages, this is because NPM cache is now considered to be dirty; it has references to two potential locations.

sudo npm cache clean --force

All global NPM packages will need to be re-installed into their new location.

Windows

Use node installer.
