If you're a Mac user, chances are you're familiar with Node.js, the platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications. But what do you do when you need to upgrade your Node version to match your project's requirements? Fear not, as this subtopic will show you how to upgrade your Mac's Node.js version using code snippets.

Upgrading your Mac's Node version is crucial when working with certain frameworks or libraries. Luckily, there are multiple ways to do it, and this subtopic will guide you through them step by step, so you can select the one that works best for you.

Whether you prefer installing and managing versions using a package manager like Homebrew or NPM, or if you want to try out an automatic version management tool like nvm, you'll find everything you need to know here. So, let's dive into the code and discover how to upgrade your Mac's Node version to your desired version!

Checking current Node version

To check the current version of Node installed on your Mac, open the terminal and type the command node -v and press enter. This will display the current version of Node installed on your Mac.

Alternatively, you can also check the version of Node installed on your Mac using the which command. Type the command which node and press enter. This will display the location of the Node installation folder.

Once you have determined the current version of Node installed on your Mac, you can proceed to upgrade it to your desired version using code snippets that are specific to your situation. The ability to check the current version of Node is useful in ensuring that you are upgrading to the desired version and that there are no conflicts with any other applications or dependencies.

Installing Node Version Manager (NVM)

Node Version Manager (NVM) is a popular tool among developers to manage multiple versions of Node.js on their machine. Installing it is straightforward, and it only requires a few steps.

Step 1: Install Homebrew (optional)

Homebrew is a package manager for macOS. If you don't have Homebrew installed on your machine, you can install it by running the following command in your terminal:

/bin/bash -c "$(curl -fsSL"

Step 2: Install NVM

To install NVM, you can use Homebrew by running the following command in your terminal:

brew install nvm

Alternatively, you can download the installation script from the NVM GitHub repository and run it manually:

curl -o- | bash

After the installation is complete, you need to restart your terminal or run the following command to apply the changes:

source ~/.zshrc

Step 3: Install a Node.js version

Now that NVM is installed, you can use it to install any Node.js version you want. For example, to install version 14.17.6, you can run the following command:

nvm install 14.17.6

To verify that the installation was successful, you can run the following command to check the Node.js version:

node -v

This should output the version number you just installed.


With NVM installed, you can easily switch between different Node.js versions and manage them independently for different projects. This can make it much easier to manage dependencies and ensure compatibility with different libraries and frameworks.

Installing desired Node version

To install a desired Node version on your Mac, you will need to use a package manager like Homebrew. Homebrew is a command-line tool that simplifies the installation of software on macOS.

First, install Homebrew by opening the Terminal app and entering the following command:

/bin/bash -c "$(curl -fsSL"

After Homebrew is installed, you can install the desired version of Node by entering the following command:

brew install node@{version}

Replace {version} with the desired version number, such as 14 or 16.

Once the installation is complete, you can check the installed version by entering the following command:

node -v

This will display the version number of the installed Node version.

In summary, installing a desired Node version on your Mac is a simple process that can be accomplished with Homebrew. By following the steps outlined above, you can quickly and easily upgrade your Mac's Node version to the one you want.

Switching between Node versions

When working with Node, it's not uncommon to need to switch between different versions. Fortunately, there are several tools available that make this process relatively painless. One popular option is NVM (Node Version Manager), which allows you to install and manage multiple Node versions on the same machine.

To switch between Node versions using NVM, you first need to install the desired version. This can be done using the command nvm install [version]. For example, if you want to install Node version 14.17.0, you would run nvm install 14.17.0.

Once the version is installed, you can switch to it using nvm use [version]. So if you want to switch to the version we just installed, you would run nvm use 14.17.0.

If you want to set a default Node version, you can use nvm alias default [version]. This will ensure that the specified version is used by default whenever you launch a new terminal session.

It's worth noting that some projects may require specific Node versions, so it's important to check the project's documentation or read-me file to ensure you have the correct version installed. Additionally, it's always a good idea to keep your Node versions up to date to take advantage of the latest features and security updates.

Checking Node version again

To check the Node version that's currently running on your Mac, you can use the "node -v" command in your terminal window. This will display the version number of the Node.js installed on your system. If you've recently upgraded your Node version, it's important to check if the new version has been successfully installed and running.

To make sure that you're running the upgraded version, you can run the "node -v" command again. This will display the version number of the Node that's currently running on your system. If the version number is the same as the previous one, it means that the new version hasn't been loaded into the system yet.

In order to switch to the upgraded version, you will need to update your PATH environment variable to point to the new version of Node. You can do this by running the following command in your terminal:

export PATH="/path/to/new/nodejs/bin:$PATH"

Replace "/path/to/new/nodejs/bin" with the path to the directory where the new Node version is located. Once you've updated your PATH, you can check the Node version again by running the "node -v" command. You should see the new version number displayed.

It's always a good idea to check your Node version again after upgrading in order to make sure that the process was successful. By following these steps, you can easily check and update your Node version as needed.


We have learned how to upgrade our Mac's Node to a desired version using various code snippets. We started by checking the current version of Node installed in our system using the node -v command. We then proceeded to install and use nvm to switch between different Node versions. We learned how to install a specific version of Node using nvm install command and how to set a default version using nvm alias command. We also discussed how to update the Node version using the nvm install --lts command.

In addition, we also covered how to upgrade Node manually by downloading the latest version from the official website and replacing the existing binary file with the downloaded one. We learned how to check the newly installed version of Node using the node -v command.

It is important to keep our Node version up to date for security and performance reasons. By following the steps outlined in this guide, one can upgrade their Mac's Node to any desired version with ease.
