How to Install and Uninstall Homebrew on macOS?

The Command-line Interface is a text-based user interface through which users can interact with their computer. Instead of using the mouse to interact, users will need to type commands as text and receive text-based feedback. However, you may not have a good package manager that lets you install free and open-source software. Homebrew is a pretty known package manager for macOS that lets you install a different type of software through the terminal. You will even need Homebrew to install the developer tools on your system. In this article, we will teach you about the installation and uninstallation of Homebrew in macOS.

Installing Homebrew on macOS

The Homebrew will install all the packages to their own director and then symbolic links their files into /usr/local. It will not install the files outside of its prefix. The user can place a Homebrew installation anywhere they like. Once Homebrew installed, users will be able to easily install software like Ruby, Git, and Python.

Important: You need to install Xcode development software from the Apple App Store before installing Homebrew.

  1. Open the Safari browser and go to the Homebrew site (brew.sh). On the home page, you will get the install command. Copy the command from there.
    /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
