What is nvm?

nvm is a version manager for node.js which lets you easily switch between different node versions. You can define an .nvmrc file in your node project which enforces the node version standardization with your codebase collaborators.

Install NVM

Install

wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bash

.bashrc

# make sure you have this code

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

.bash_profile

if [ -f ~/.bashrc ]; then
    source ~/.bashrc
fi

You have to exit the Terminal then open again for the change to take effect.

Use nvm

Create a .nvmrc file in the same directory as your package.json.

Run nvm use before you run npm install or yarn.
