• Install Homebrew.

• Install Node:

    brew install node
  

• Install NVM:

    brew install nvm
  

You should create NVM's working directory if it doesn't exist:

mkdir ~/.nvm

Add the following to ~/.zshrc or your desired shell configuration file:

export NVM_DIR="$HOME/.nvm" . "$(brew --prefix nvm)/nvm.sh"

You can set $NVM_DIR to any location, but leaving it unchanged from /usr/local/Cellar/nvm/0.31.1 will destroy any nvm-installed Node installations upon upgrade/reinstall.

Type nvm help for further information.

Bash completion has been installed to: /usr/local/etc/bash_completion.d

    source $(brew --prefix nvm)/nvm.sh
