Installation

Instructions for a supported install of Homebrew are on the homepage.

This script installs Homebrew to its preferred prefix (/usr/local for macOS Intel, /opt/homebrew for Apple Silicon and /home/linuxbrew/.linuxbrew for Linux) so that you don’t need sudo when you brew install. It is a careful script; it can be run even if you have stuff installed in the preferred prefix already. It tells you exactly what it will do before it does it too. You have to confirm everything it will do before it starts.

macOS Requirements

Git Remote Mirroring

You can use geolocalized Git mirrors to speed up Homebrew’s installation and brew update by setting HOMEBREW_BREW_GIT_REMOTE and/or HOMEBREW_CORE_GIT_REMOTE in your shell environment with this script:

export HOMEBREW_BREW_GIT_REMOTE="..."  # put your Git mirror of Homebrew/brew here
export HOMEBREW_CORE_GIT_REMOTE="..."  # put your Git mirror of Homebrew/homebrew-core here
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

The default Git remote will be used if the corresponding environment variable is unset.

Skip Tap Cloning (beta)

You can instruct Homebrew to skip cloning the Homebrew/homebrew-core tap during installation by setting the beta HOMEBREW_INSTALL_FROM_API environment variable with the following:

export HOMEBREW_INSTALL_FROM_API=1
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

This will make Homebrew install formulae and casks in homebrew/core and homebrew/cask taps using Homebrew’s API instead of local checkouts of these repositories.

Alternative Installs

Linux or Windows 10 Subsystem for Linux

Check out the Homebrew on Linux installation documentation.

Untar anywhere

Just extract (or git clone) Homebrew wherever you want. Just avoid:

However do yourself a favour and use the installer to install to the default prefix. Some things may not build when installed elsewhere. One of the reasons Homebrew just works relative to the competition is because we recommend installing here. Pick another prefix at your peril!

mkdir homebrew && curl -L https://github.com/Homebrew/brew/tarball/master | tar xz --strip 1 -C homebrew

or

git clone https://github.com/Homebrew/brew homebrew

then

eval "$(homebrew/bin/brew shellenv)"
brew update --force --quiet
chmod -R go-w "$(brew --prefix)/share/zsh"

Multiple installations

Create a Homebrew installation wherever you extract the tarball. Whichever brew command is called is where the packages will be installed. You can use this as you see fit, e.g. to have a system set of libs in the default prefix and tweaked formulae for development in ~/homebrew.

Unattended installation

If you want a non-interactive run of the Homebrew installer that doesn’t prompt for passwords (e.g. in automation scripts), prepend NONINTERACTIVE=1 to the installation command.

Uninstallation

Uninstallation is documented in the FAQ.

1 For 32-bit or PPC support see Tigerbrew.

2 10.15 or higher is recommended, while 10.11–10.14 are supported on a best-effort basis. For 10.4–10.6 see Tigerbrew.

3 Most formulae require a compiler. A handful require a full Xcode installation. You can install Xcode, the CLT, or both; Homebrew supports all three configurations. Downloading Xcode may require an Apple Developer account on older versions of Mac OS X. Sign up for free at Apple’s website.

4 The one-liner installation method found on brew.sh requires the Bourne-again shell, i.e. bash. Notably, zsh, fish, tcsh and csh will not work.
