Install nvm-ng

• If you use nvm via the zsh-plugin, disable it by removing nvm from the plugins of your ~/.zshrc
• If you have nvm installed via the install-script from creationix, unistall it as described here
• do a regular nvm-ng-install as described here

BE SURE TO NOT HAVE A PREFIX CONFIGURED IN NPM!!!

Setting a prefix changes the installation directory for global packages and is not supported by nvm.

if npm config get prefix is either not set, or a subpath of echo $NVM_DIR, then you're good to go. Otherwise run npm config delete prefix to unset your prefix.

Setup fast-reuse

In the file where nvm gets initialized (~/.zshrc or ~/.bashrc) add --fast-reuse to the line that reads

[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"

Initializing nvm should then look like this:

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" --fast-reuse # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion
