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

Question

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

use oh-my-zsh plugins [`zsh-nvm`](https://github.com/lukechilds/zsh-nvm) — Yossarian42, Mar 31 '20 at 02:43

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 $@
}

If anyone is using Vim for development, the lazy loading causes autocompletion using tsserver to fail because tsserver won't be found in PATH. Best to just use eager loading IMHO. – geoyws Oct 27 '19 at 03:48
If I add this to ~/.zshrc, I get "command not found" when running nvm? How do I use this? – Petrus Theron Oct 21 '20 at 10:53
make sure your .zshrc has been loaded: you can type "lazy" and press Tab to see if the ZSH auto-completion shows you lazynvm. if not, check your shell config or ZSH config to make sure it's loading the `.zshrc` – Ryan Wu Oct 23 '20 at 14:04
If using oh-my-zsh, the nvm plugin already has lazy loading implemented, so skip to the next answer. – javs Feb 17 '22 at 16:38
For anyone wondering `[ -s "$NVM_DIR/nvm.sh" ]` => `-s FILE - True if the FILE exists and has nonzero size` – Kellen Stuart Nov 08 '22 at 18:19

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:

Open your zsh config file.zshrc in nano with this command: nano ~/.zshrc
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)
Press control + O (on macOS), then enter, to save, then press control + X to exit
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.)

Thanks for the detailled answer. I think the only way to improve this answer is: Adding a Header (Moved from Bash to zsh) and add some linebreaks – duichwer Aug 29 '19 at 14:10

we ran into this issue because we had oh-my-zsh on top of basic zsh. Thanks for the answer. – Khwaja Sanjari Jun 20 '23 at 17:35

This worked for me on Ubuntu 20.04.

Install or update nvm

wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.37.2/install.sh | bash

Run the following commands in your terminal to add to 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

brew install nvm
edit your system configuration

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

esc > :wq
save file

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

$ nvm --version
# 0.36.0

enjoy it.

`source $(brew --prefix nvm)/nvm.sh` was the missing piece for me. Thanks! – Aurelio Dec 02 '20 at 13:43
Thanks, this solved my issue. Glad I tried this before doing any reinstallation. – yoges nsamy Jun 19 '21 at 00:46

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

git clone https://github.com/nvm-sh/nvm.git ~/.nvm
cd ~/.nvm && git checkout v0.35.1 (current latest release)
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.

As of this writing, adding `nvm` as a plugin did not work for me on a Mac (OS should not be a factor, though). I still get `zsh: command not found: nvm`. I'll try adding manually. – Mike S. Jun 20 '20 at 12:54
I'm having the same issue. May I know what you mean by `adding manually`? – yoges nsamy Jun 19 '21 at 00:30
To get [zsh-nvm](https://github.com/lukechilds/zsh-nvm) working, I had to find the section in the README [how to install plugin](https://github.com/lukechilds/zsh-nvm#as-an-oh-my-zsh-custom-plugin). Steps involved: `git clone https://github.com/lukechilds/zsh-nvm ~/.oh-my-zsh/custom/plugins/zsh-nvm` and I had to edit the `~/.zshrc` file and to add the plugin `plugins=( git zsh-nvm )`. Loaded new terminal and `nvm list` finally worked. – Dave Boster Nov 18 '22 at 22:29

With Linux (Ubuntu 20.04, 22.04, 22.10 and 23.04)

With your favorite editor, you edit ~/.zshrc

nano or vi ~/.zshrc

At the end of the file, you add :

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

And then you run :

source ~/.zshrc

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

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
