How to run "nvm" in "oh my zsh"?

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

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.)

This worked for me on Ubuntu 20.04.

Install or update nvm

wget -qO- | bash 

Add in your ~/.zshrc

echo 'export NVM_DIR=~/.nvm' >> ~/.zshrc echo '[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh"' >> ~/.zshrc 

Load in the current shell environment

source ~/.zshrc 

Check the nvm version

nvm -v 

use homebrew to install nvm

1. brew install nvm

2. edit your system configuration

 vim ~/.zshrc # or vim ~/.bashrc export NVM_DIR=~/.nvm 

esc > :wq
save file

3. reload the configuration
   source $(brew --prefix nvm)/nvm.sh

4. view nvm version

$ nvm --version # 0.36.0 

enjoy it.

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 ~/.nvm
2. cd ~/.nvm && git checkout v0.35.1 (current latest release)
3. Add nvm to your ~/.zshrc. Ex: plugins=(... nvm)

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.

Add this code to .zshrc on your user directory

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 

Then run this code on your terminal:

source ~/.zshrc 

With Linux (Ubuntu 20.04 - 22.04)

With your favorite editor, you edit ~/.zshrc

nano or vi ~/.zshrc 

At the end of the file your add:

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

And then you run:

source ~/.zshrc 

I strongly suggest using christophemarois' approach to lazy loading nvm (node, npm and global packages) in order to avoid slow shell starting times:

# Add every binary that requires nvm, npm or node to run to an array of node globals NODE_GLOBALS=(`find ~/.nvm/versions/node -maxdepth 3 -type l -wholename '*/bin/*' | xargs -n1 basename | sort | uniq`) NODE_GLOBALS+=("node") NODE_GLOBALS+=("nvm") # Lazy-loading nvm + npm on node globals call load_nvm () { export NVM_DIR=~/.nvm [ -s "$(brew --prefix nvm)/nvm.sh" ] && . "$(brew --prefix nvm)/nvm.sh" } # Making node global trigger the lazy loading for cmd in "${NODE_GLOBALS[@]}"; do eval "${cmd}(){ unset -f ${NODE_GLOBALS}; load_nvm; ${cmd} \$@ }" done
