Installing Homebrew

One installer for every developer tool you’ll ever need.

Homebrew is the app store for developer tools, minus the store: one command installs almost anything. You'll use it constantly, so set it up once now. (It needs Xcode Command Line Tools in place first, which was the last chapter.)

1. 1

   Open your terminal and paste this in:

   TerminalCopy

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

2. 2

   Press Enter. It asks for your Mac login password, so type it and press Enter. (Nothing appears as you type. That's a terminal security habit, not a broken keyboard.)

3. 3

   It asks you to confirm with Enter one more time, then runs for a few minutes.

4. 4

   At the end it prints “Next steps” with a command or two. These teach your terminal the brew command, so copy them from your own terminal output and run them. They'll look like:

   TerminalCopy

   eval "$(/opt/homebrew/bin/brew shellenv zsh)"

5. 5

   Sanity check time. Paste this:

   TerminalCopy

   brew --version

6. 6

   Press Enter. A version number means it worked.

Homebrew's in. From here, installs are one-liners.
