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

[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:
