Fixing npm On Mac OS X; When npm install -g does not work

mac-osx-node-npm.md

Nuke Everything node/npm related

(If you have setup another prefix)
rm -rf .npm-global

sudo rm -rf /usr/local/lib/node_modules
sudo rm -rf ~/.npm
brew uninstall node --ignore-dependencies node
rm -rf /usr/local/lib/node_modules

Install node (includes npm) from the nodejs website

To avoid using sudo with npm

sudo chown -R $(whoami) $(npm config get prefix)/{lib/node_modules,bin,share}

Having the same issue! However, brew is giving me the following error:

brew uninstall node --ignore-dependencies --force node

Uninstalling node... (304 files, 2.3MB)
Error: Could not remove /usr/local/Cellar/node/8.2.1! Check its permissions.
