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

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:
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.)

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
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
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.

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.

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 and 22.10)
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

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

ZSH shell on Ubuntu WSL can't find node, npm, nvm or any other installations after PATH adjustment

I installed Ubuntu using WSL2 on Windows 11 and configured oh-my-zsh as my default shell. After that, I created /etc/wsl.conf and added the following lines:
[interop]
appendWindowsPath=false
to not include the Windows PATH in WSL. Now, my zsh shell can't pick any installation like node, npm or vscode. It must be because of some config edit I need to make in ~/.zshrc configuration file. What am I supposed to do here?
Add these few lines in the .zshrc file:
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion" # This loads nvm bash_comp$

Node reverts to old version and NVM disappears when I close terminal and restart

Issue
I have installed NVM. Each time I close the terminal and open it back up, NVM disappears and my node version rolls back from 14 to 12.
Every time I open my terminal back up, I notice the node version rolls back. I try to use nvm, and will get bash: nvm: command not found. I have to run this script again to get it working every time.
export NVM_DIR="$([ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm")"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
I noticed the meta description when you google NVM says it's designed to be used per-user and invoked per shell. However, the setup article linked in the first SO post below mentioned installing, killing the terminal, and opening it back up with nvm still being loaded.
Anyone know what I can do so that I don't have to reinstall nvm every time I open the terminal?
Steps taken to resolve
I have reviewed this SO post and also this one. From those two I have tried the following suggestions:
I have run nvm alias default v14.17.1 in my root directory
I have pasted the following script into both .zshrc and .bashrc
export NVM_DIR="$([ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm")"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
Edit: I am on MacOS Big Sur 11.5.2

How to get new terminal windows to have node version 12 instead of 10?

I've installed node version 12 using the below commands.
$ nvm install 12 -g
# note - nvm use 12.13.1 has same effect
v12.13.1 is already installed.
Now using node v12.13.1 (npm v6.12.1)
When I type $ node -v to confirm the node version, the command line reads v12.13.1.
I have also set it as my default node version.
$ nvm alias default 12.13.1
default -> 12.13.1 (-> v12.13.1)
Yet when I open a new window I still see version 10.
$ node -v
v10.17.0
and I have to
$ nvm use 12
every time I open a new window
and then I have
$ node -v
v12.13.1
How can I have 12 be my default without doing use every time ?
This is on Ubuntu, my .bashrc includes:
export NVM_DIR="$([ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm")"
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion" # This loads nvm bash_completion
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
I removed npm by removing the ~/.npm folder and then reinstalled npm with:
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.1/install.sh | bash
and version 12 of node with
nvm install 12
node -v
This fixed it and now new terminal windows now show
node -v
v12.13.1

How to enable nvm in steps in circleci 2.0?

Here are my steps in my
steps:
-run:
name: Setup nvm and npm
command: |
wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.33.8/install.sh | bash
export NVM_DIR=$HOME/.nvm
source $NVM_DIR/nvm.sh
nvm install 8.9 && nvm alias default 8.9
-run: npm install && npm run lint && npm test
The second step always fails with this error message
/bin/bash: npm: command not found
I checked .bashrc and I can see the following lines are added to the end of the file
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion" # This loads nvm bash_completion
Circleci 2.0 invokes the step command by starting a new shell with #!/bin/bash -eo pipefail
If I starts a docker (docker run -i -t buildpack-deps:xenial) and apply the first step, and then start a new shell via #!/bin/bash -eo pipefail, I can see npm is available on the path
I am using docker for this project
version: 2
jobs:
test_main:
docker:
- image: buildpack-deps:xenial
So why does it fail in circleci 2.0 environment? How can I ensure npm will be available to step 2 from step 1?
I have tried to add [ -s "$HOME/.bashrc" ] && \. "$HOME/.bashrc" to ~/.bash_profile (in case .bashrc is not executed due to the non-interactive/non-login shell)
To reproduce the issue you can run circleci build with this .circleci/config.yml file
version: 2
jobs:
build:
docker:
- image: buildpack-deps:xenial
steps:
- run:
name: Setup nvm and npm
command: |
wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.33.8/install.sh | bash
# Activate nvm
export NVM_DIR=$HOME/.nvm
touch $HOME/.nvmrc
source $NVM_DIR/nvm.sh
# Use node 8.9
nvm install 8.9 && nvm alias default 8.9
echo 8.9 > $HOME/.nvmrc
# Enable nvm in following steps
echo '[ -s "$HOME/.bashrc" ] && \. "$HOME/.bashrc"' >> $HOME/.bash_profile
# To fix npm install : "node-pre-gyp: Permission denied"
npm config set user 0
npm config set unsafe-perm true
npm install -g npx webpack webpack-cli jest
node --version
npm --version
- run: npm install
You will see the following error message:
====>> npm install
#!/bin/bash -eo pipefail
npm install
/bin/bash: npm: command not found
Error: Exited with code 127
Step failed
Task failed
The problem lies with these lines:
# Enable nvm in following steps
echo '[ -s "$HOME/.bashrc" ] && \. "$HOME/.bashrc"' >> $HOME/.bash_profile
I was hoping to source .bashrc from .bash_profile. However since the shell of circleci is non-interactive, the environment variable PS1 is blank. Hence .bashrc basically quits immediately once it is sourced, because of this line in .bashrc
# If not running interactively, don't do anything
[ -z "$PS1" ] && return
I have to put the following lines directly in the file specified by $BASH_ENV
echo 'export NVM_DIR=$HOME/.nvm' >> $BASH_ENV
echo 'source $NVM_DIR/nvm.sh' >> $BASH_ENV
I found that changing default node by nvm is not working for my steps.
Solved by:
- run:
name: 'Install Project Node'
command: |
set +x
source ~/.bashrc
nvm install 12
NODE_DIR=$(dirname $(which node))
echo "export PATH=$NODE_DIR:\$PATH" >> $BASH_ENV
Just source /opt/circleci/.nvm/nvm.sh in the beginning of every step.

zsh: command not found: modernizr

I installed modernizr: npm install -g modernizr
Everything went well without errors: /Users/myusername/npm/bin/modernizr -> /Users/myusername/npm/lib/node_modules/modernizr/bin/modernizr
/Users/myusername/npm/lib
After install running: modernizr I get:
zsh: command not found: modernizr
In my .zshrc file I have:
export PATH="/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin"
After googling around find this post: Bower: "command not found" after installation and added this line to my .zshrc file: export PATH=/usr/local/share/npm/bin:$PATH
When I type which npm I get /usr/local/bin/npm
But I'm still getting command not found.
I checked files with Mac Finder and found modernizer in myusername/npm/node_modules/modernizer - this should be right? How to fix zsh command not found?
Change PATH export to
export PATH=$PATH:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:$HOME/npm/bin
You can also remove the double quotes.
For WSL2 + NVM user:
Add following to the end of ~/.zshrc
***ignore last line if bash_completion not installed
export NVM_DIR="$([ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm")" #npm package
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" #loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion" #loads nvm bash_completion
Restart terminal
