This tutorial goes through installing Node Version Manager (NVM) on Ubuntu / Ubuntu like systems (I am using Linux Mint 21.2 Cinnamon). According to the devs: “nvm is a version manager for node.js, designed to be installed per-user, and invoked per-shell. nvm works on any POSIX-compliant shell (sh, dash, ksh, zsh, bash), in particular on these platforms: unix, macOS, and windows WSL.” NVM makes managing different node.js versions extremely simple. The official github repo can be found here: https://github.com/nvm-sh/nvm.
First off we need to install NVM, we have a few options such as via curl or wget, or we could manually download and run the script. We will use either curl or wget.
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash
wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash
Running either of these commands will download the script and run it. The official docs get much deeper into this see: https://github.com/nvm-sh/nvm. You should now have NVM installed. Just be sure to reload your terminal with:
source ~/.bashrc # assuming you are using bash
Once NVM is installed run nvm –help to display all of the available commands etc. a few of the basics are below:
nvm --version # displays version of node.js
nvm install [<version>] # Download and install a <version>. Uses .nvmrc if available and version is omitted.
nvm uninstall <version> # Uninstall a version
nvm use [<version>] # Modify PATH to use <version>. Uses .nvmrc if available and version is omitted.
nvm ls [<version>] # List installed versions, matching a given <version> if provided
and a full copy of nvm –help:
: 'Node Version Manager (v0.39.7)
Note: <version> refers to any version-like string nvm understands. This includes:
- full or partial version numbers, starting with an optional "v" (0.10, v0.1.2, v1)
- default (built-in) aliases: node, stable, unstable, iojs, system
- custom aliases you define with `nvm alias foo`
Any options that produce colorized output should respect the `--no-colors` option.
Usage:
nvm --help Show this message
--no-colors Suppress colored output
nvm --version Print out the installed version of nvm
nvm install [<version>] Download and install a <version>. Uses .nvmrc if available and version is omitted.

nvm exec 4.8.3 node app.js Run `node app.js` with the PATH pointing to node 4.8.3
nvm alias default 8.1.0 Set default node version on a shell
nvm alias default node Always default to the latest available node version on a shell
nvm install node Install the latest available version
