The suggested and easiest way to install Homebrew is on the homepage.
The standard script installs Homebrew to
/usr/local 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
/usr/local already. It tells you exactly what it will do before
it does it too. And you have to confirm everything it will do before it starts.
xcode-select --install, developer.apple.com/downloads or Xcode 3
Because GitHub now only allows clients that support TLS 1.2 to access repositories over HTTPS, the Homebrew installer will use the Git protocol when run on systems older than OS X Mavericks (10.9). This requires the availability of a
git binary, which can be provided by pre-installing the Command Line Tools for Xcode. Homebrew will also require the Command Line Tools or Xcode in order to automatically compile and install a newer
git with support for TLS 1.2.
Just extract (or
git clone) Homebrew wherever you want. Just avoid:
/tmpsubdirectories because Homebrew gets upset.
/opt/localbecause build scripts get confused when Homebrew is there instead of Fink or MacPorts, respectively.
However do yourself a favour and install to
/usr/local. Some things may
not build when installed elsewhere. One of the reasons Homebrew just
works relative to the competition is because we recommend installing
/usr/local. Pick another prefix at your peril!
mkdir homebrew && curl -L https://github.com/Homebrew/brew/tarball/master | tar xz --strip 1 -C homebrew
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. a system set of libs in
/usr/local and tweaked formulae for development in
Uninstallation is documented in the FAQ.
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 here.
