to have a system set of libs in the default prefix and tweaked formulae for development in ~/homebrew. Whichever brew command is called is where the packages will be installed.

/sw and /opt/local because build scripts get confused when Homebrew is there instead of Fink or MacPorts, respectively.Ĭreate a Homebrew installation wherever you extract the tarball.

/tmp subdirectories because Homebrew gets upset.

Homebrew itself can handle spaces, but many build scripts cannot.

Directories with names that contain spaces.

TL DR: pick another prefix at your peril!īrew update -force -quiet chmod -R go-w ' $(brew -prefix ) /share/zsh'

If you decide to use another prefix: don’t open any issues, even if you think they are unrelated to your prefix choice. The main reason Homebrew just works is because we use bottles (binary packages) and most of these require using the default prefix. Building from source is slow, energy-inefficient, buggy and unsupported. Many things will need to be built from source outside the default prefix. However, you shouldn’t install outside the default, supported, best prefix. Technically, you can just extract (or git clone) Homebrew wherever you want. Alternative Installs Linux or Windows 10 Subsystem for LinuxĬheck out the Homebrew on Linux installation documentation. in automation scripts), prepend NONINTERACTIVE=1 to the installation command. If you want a non-interactive run of the Homebrew installer that doesn’t prompt for passwords (e.g. using the default Homebrew prefix and, if on macOS, on a supported version). Note, this will take effect in supported configurations (i.e.

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

You have to confirm everything it will do before it starts. It tells you exactly what it will do before it does it too. It is a careful script it can be run even if you have stuff installed in the preferred prefix already. This prefix is required for most bottles (binary packages) to be used. This script installs Homebrew to its default, supported, best prefix ( /usr/local for macOS Intel, /opt/homebrew for Apple Silicon and /home/linuxbrew/.linuxbrew for Linux) so that you don’t need sudo after Homebrew’s initial installation when you brew install. Instructions for a supported install of Homebrew are on the homepage.
