How to run “nvm” in “oh my zsh”?

问题

In the system there is a nodejs, installed through nvm. The command is not running npm. Console is Oh my zsh

回答1:

You can use zsh-nvm or enable it yourself by adding following lines to your ~/.zshrc

 export NVM_DIR=~/.nvm
 [ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh"

Extra:

For faster shell initialization, I use lazynvm which only loads node when needed

lazynvm() {
  unset -f nvm node npm
  export NVM_DIR=~/.nvm
  [ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh"  # This loads nvm
}

nvm() {
  lazynvm 
  nvm $@
}

node() {
  lazynvm
  node $@
}

npm() {
  lazynvm
  npm $@
}

Switching from Bash to Oh-My-Zsh

If you already have nvm installed and you're switching from bash to oh-my-zsh you can simply open up your .zshrc file and add the nvm plugin that is included with oh-my-zsh:

1. Open your zsh config file.zshrc in nano with this command: nano ~/.zshrc
2. Scroll down to where it shows plugins=(git) and add nvm inside the parentheses to make it show as plugins=(git nvm) (separate plugins with spaces)
3. Press control + O (on macOS), then enter, to save, then press control + X to exit
4. Then open a new terminal window/tab and enter nvm ls to confirm it works. Note that you must open a new window/tab for your shell to use the newly updated .zshrc config (or enter source ~/.zshrc, etc.)

I discovered that there is a nvm plug-in shipping with oh-my-zsh (that's different from lukechilds plugin). After short inspection, I think it adds the necessary modifications to .zshrc when loading, so simply adding nvm to the plugins list in .zshrc should work as well (and it does for me).

I did not find any more details on that default nvm plugin via google so I don't know whether this is the "go-to" solution.

A much easier solution is to use the nvm plugin that is shipped by default:

It also automatically sources nvm, so you don't need to do it manually in your .zshrc

1. git clone https://github.com/nvm-sh/nvm.git ~/.nvm
2. cd ~/.nvm && git checkout v0.35.1 (current latest release)
3. Add nvm to your ~/.zshrc. Ex: plugins=(... nvm)
