Managing multiple Node.js versions on your Mac can be a real challenge. Fortunately, with Node Version Manager (NVM), you can effortlessly switch between different versions, streamlining your development setup and reducing potential conflicts. This guide provides a clear checklist on how to install nvm in mac, ensuring you can configure and use it with ease.
NVM, or Node Version Manager, is a tool designed to help developers manage multiple Node.js versions on a single machine. It simplifies the management of dependencies across various projects. By using a few simple commands, you can install, switch, and uninstall Node.js versions without conflict.
Installing NVM offers numerous advantages:
It makes switching between Node.js versions simple and efficient.
You can manage dependencies for different projects easily.
NVM helps reduce conflicts that may arise with system-installed Node.js.
Before you begin, ensure your system meets the necessary requirements:
Your macOS should be up-to-date. A recent version is recommended.
You may need tools such as Homebrew, curl, or wget to install NVM efficiently.
Take the following steps to ensure your system is ready for NVM:
Update your macOS to the latest version available.
If Homebrew is not installed, install it to manage other dependencies smoothly.
Verify your default terminal shell (commonly zsh or bash) to know where to add configuration details.

Start by using the official curl or wget command from the NVM GitHub repository to download the installation script. Running the script will setup nvm installation guide mac for you. Ensure you review the script and then execute it in your terminal.
Once installed, add the NVM configuration to your shell profile. Open your ~/.zshrc or ~/.bashrc file and insert the necessary configuration lines. After making these changes, reload your shell configuration. This is one of the essential mac nvm installation steps to activate NVM properly.
To check if NVM is successfully installed, run the command nvm --version in your terminal. If you encounter errors such as a message indicating command not found, recheck your profile configuration and environment variables.

Changing Node.js versions is straightforward. Simply use the command nvm use <version> to activate the version you need. For convenience, set a default version with nvm alias default <version> to ensure that every new terminal session starts with the right version. This makes it easier to setup nvm on mac efficiently.
Beyond installation and switching versions, NVM offers other useful commands:
List all installed Node.js versions with nvm list.
If necessary, remove an unwanted version using nvm uninstall <version>.
Encountering issues during installation is not uncommon. Here are some fixes:
