Introduction

As a Node.js developer, you may find yourself needing to switch between different versions of Node.js for different projects. This can be time-consuming and frustrating without the right tools. Node Version Manager (NVM) is a tool that allows you to easily manage multiple versions of Node.js on your computer. In this comprehensive guide, we will walk you through the installation and usage of NVM on both Windows and Mac OS. We will also cover common issues and troubleshooting tips to help you get the most out of this powerful tool.

What is NVM

Node Version Manager (NVM) is a tool that allows you to easily manage multiple versions of Node.js on your computer. NVM makes it easy to switch between different versions of Node.js for different projects, and it also provides a way to quickly switch back to a previous version if you encounter issues with a newer version. NVM is available for both Windows and Mac OS, and it is a popular tool among Node.js developers.

Installation on Windows

  1. Download the NVM installation package from the NVM for Windows GitHub page.

  2. Run the installation package and follow the prompts to complete the installation.

  3. Open a new command prompt or terminal window and run the command nvm to ensure that NVM was installed correctly.

  4. To install a specific version of Node.js, run the command nvm install [version]. For example, to install Node.js version 14.16.0, run the command nvm install 14.16.0.

  5. To switch to a specific version of Node.js, run the command nvm use [version]. For example, to switch to Node.js version 14.16.0, run the command nvm use 14.16.0.

Installation on Mac OS:

  1. Open the Terminal application.

  2. Install Homebrew by running the command /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)".

  3. Install NVM by running the command brew install nvm.

  4. To enable NVM, add the following line to your .bash_profile or .zshrc file: export NVM_DIR="$HOME/.nvm" [ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" # This loads nvm.

  5. Close and reopen the terminal window, or run the command source ~/.bash_profile or source ~/.zshrc.

  6. To install a specific version of Node.js, run the command nvm install [version]. For example, to install Node.js version 14.16.0, run the command nvm install 14.16.0.

  7. To switch to a specific version of Node.js, run the command nvm use [version]. For example, to switch to Node.js version 14.16.0, run the command nvm use 14.16.0.

Usage:

Once you have NVM installed, using it is easy. Here are some common commands that you will use with NVM:

  • nvm install [version]: Installs a specific version of Node.js.
  • nvm use [version]: Switches to a specific version of Node.js.
  • nvm list: Lists all installed versions of Node.js.
