Easy way to install nvm on Ubuntu 18.04

Nvm — Node version manager

As the name suggests, nvm allows you to run multiple versions of nodejs on your PC.

• Example usage:

$ nvm install 10.0.0    # Install node version 10.0.0
$ nvm use 10.0.0        # Use node version 10 (if it is installed)
$ nvm run 10.0 app.js   # Run app.js using node version 10.0.x
$ nvm --help            # read full nvm manual

Step 1: Download and install package

$ curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.0/install.sh | bash
# Alternatively 
$ wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash

Sample output after downloading and running the install script

Step 2: Configuration

$ export NVM_DIR="$HOME/.nvm"    
$ [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"
$ [ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"

• Line 1: Add $NVM_DIR environment variable on your current shell session
• Line 2: Run nvm.sh script if it exists, i.e. [ -s “$NVM_DIR/nvm.sh” ]
• Line 3: Run bash_completion script if it exists

Step 3: Verify your installation

• Check the installed version, by running:

$ nvm --version
# Sample output: 0.35.3
