Installing NVM and Node.js on Ubuntu

Install NVM (Node Version Manager)

1. Update your package index:

   sudo apt update

2. Install prerequisites:

   sudo apt install curl build-essential -y

3. Download and run the NVM installation script:

   curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.5/install.sh | bash

4. Close and reopen your terminal, or run this to apply changes immediately:

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

5. Verify NVM installation:

   nvm --version

Install Node.js using NVM

1. To install the latest LTS (Long Term Support) version:

   nvm install --lts

   Or install a specific version:

   nvm install 18.18.0

2. Set your default Node.js version:

   nvm alias default 'lts/*'

   Or specify a version:

   nvm alias default 18.18.0

3. Verify the installation:

   node --version
   npm --version

Managing Node.js Versions with NVM

• List installed versions:

  nvm ls

• List available versions to install:

  nvm ls-remote

• Switch between versions:

  nvm use 16.20.0

NVM makes it easy to switch between different Node.js versions for different projects.
