Are you a Mac user looking to install NVM? Look no further! This article will guide you through the process of installing NVM on your Mac in a few simple steps.

Introduction

NVM, or Node Version Manager, is a tool that allows users to manage multiple versions of Node.js on a single machine. This is especially useful for developers who need to work on projects that require different versions of Node.js. Installing NVM on your Mac is a straightforward process that can be completed in just a few minutes.

Preparing for Installation

Before you begin the installation process, there are a few things you need to do to prepare your Mac.

Checking Mac OS Version

The first step is to check your Mac OS version. NVM requires at least macOS 10.12 or later to run. To check your Mac OS version, click on the Apple icon in the top left corner of your screen and select “About This Mac.” The version number will be displayed under the macOS or OS X heading.

Installing Homebrew

The second step is to install Homebrew, a package manager for macOS. Homebrew makes it easy to install and manage software packages on your Mac. To install Homebrew, open Terminal and enter the following command:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Once the installation is complete, you can verify that Homebrew is installed correctly by running the following command:

brew --version

If Homebrew is installed correctly, you should see the version number displayed in the Terminal window.

Installing NVM

Once you have prepared your Mac, it’s time to install NVM. Follow these steps to download and install NVM on your Mac:

Downloading NVM

Open Terminal and enter the following command to download and install NVM:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash

This will download the installation script and run it on your Mac.

Running NVM Installation Script

After the download is complete, the NVM installation script will run. Follow the prompts to complete the installation process. Once the installation is complete, you can verify that NVM is installed correctly by running the following command:

nvm --version

If NVM is installed correctly, you should see the version number displayed in the Terminal window.

Configuring NVM

Now that NVM is installed on your Mac, you can configure it to suit your needs.

Adding NVM to Bash Profile

To make NVM available every time you open a new Terminal window, you need to add it to your Bash profile. To do this, open Terminal and enter the following command:

nano ~/.bash_profile

This will open your Bash profile in the Nano text editor. Add the following line to the end of the file:

source ~/.nvm/nvm.sh

Save the file and exit Nano by pressing Ctrl + X, then Y, and then Enter.

Setting up Default No-js Version

Finally, you can set up a default version of Node.js to use with NVM. To do this, enter the following command in Terminal:

nvm alias default [version]

Replace [version] with the version of Node.js you want to set as the default. For example, if you want to set Node.js version 14.17.0 as the default, enter:

nvm alias default 14.17.0

You can now use NVM to install and manage different versions of Node.js on your Mac.

Verifying NVM Installation

After installing NVM on your Mac, it’s essential to verify that it was installed correctly. Here are two simple commands you can use to check the NVM and Node.js versions:

Checking NVM Version

To check the version of NVM that you installed, open Terminal and enter the following command:

nvm --version

If NVM was installed correctly, you should see the version number displayed in the Terminal window.

Checking Node.js Version

To check the version of Node.js that you installed with NVM, open Terminal and enter the following command:

node --version

If Node.js was installed correctly, you should see the version number displayed in the Terminal window.

In conclusion, installing NVM on your Mac is a simple process that can be completed in just a few steps. By following the steps outlined in this article, you can easily manage multiple versions of Node.js on your Mac.
