Mac is a very popular computer operating system. When developers perform web development on Mac, they need to install the Node.js environment to run their own JavaScript code. This article will introduce how to install the Node.js environment on Mac.

Step One: Install Homebrew

Homebrew is a very popular package manager on Mac. First, we need to install Homebrew. Open the Terminal and enter the following command:

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

After running the command, the system will automatically download and install Homebrew. During the installation process, you need to enter the administrator password.

Step 2: Install Node.js

Now, we can use Homebrew to install Node.js. Enter the following command in the terminal:

brew install node

This command will automatically download and install the latest version of Node.js. After the installation is complete, you can use the following command to check the installation of Node.js:

node -v

If Node.js is successfully installed, the Node.js version number will be output.

Step 3: Set environment variables

After the installation is complete, we need to set environment variables to use Node.js commands in the terminal. Open the terminal and enter the following command:

echo 'export PATH="/usr/local/opt/node/bin:$PATH"' >> ~/.bash_profile

The above command will add the path of Node.js to the system environment variable. Now, we reopen a terminal window and can use Node.js commands.

At this point, we have successfully installed the Node.js environment on Mac. Through this environment, we can happily carry out web development work.
