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"
[ -s "/usr/local/opt/nvm/nvm.sh" ] && . "/usr/local/opt/nvm/nvm.sh"  # This loads nvm
[ -s "/usr/local/opt/nvm/etc/bash_completion.d/nvm" ] && . "/usr/local/opt/nvm/etc/bash_completion.d/nvm"  # This loads nvm bash_completion

node.js

nvm install --lts
