The supported method of installing specific versions of some formulae is to see if there is a versioned formula (e.g. gcc@6
) available. If the version you’re looking for isn’t available, consider opening a pull request!
You can browse pull requests and install through the direct link. For example, Python 3.3.0 from pull request Homebrew/homebrew#15199:
brew install https://raw.github.com/dsr/homebrew/9b22d42f50fcbc5e52c764448b3ac002bc153bd7/Library/Formula/python3.rb
/usr/local
brew unlink <formula>
This can be useful if a package can’t build against the version of something you have linked into /usr/local
.
And of course, you can simply brew link <formula>
again afterwards!
brew info <formula> brew switch <formula> <version>
Use brew info <formula>
to check what versions are installed but not currently activated, then brew switch <formula> <version>
to activate the desired version. This can be useful if you would like to switch between versions of a formula.
./configure --prefix=/usr/local/Cellar/foo/1.2 && make && make install && brew link foo
Sometimes it’s faster to download a file via means other than those strategies that are available as part of Homebrew. For example, Erlang provides a torrent that’ll let you download at 4–5× the normal HTTP method.
Download the file and drop it in ~/Library/Caches/Homebrew
, but watch the file name. Homebrew downloads files as <formula>-<version>
. In the case of Erlang, this requires renaming the file from otp_src_R13B03
to erlang-R13B03
.
brew --cache -s erlang
will print the correct name of the cached download. This means instead of manually renaming a formula, you can run mv the_tarball $(brew --cache -s <formula>)
.
You can also pre-cache the download by using the command brew fetch formula
which also displays the SHA-256 hash. This can be useful for updating formulae to new versions.
brew sh # or: eval $(brew --env) gem install ronn # or c-programs
This imports the brew
environment into your existing shell; gem
will pick up the environment variables and be able to build. As a bonus brew
’s automatically determined optimization flags are set.
brew install --only-dependencies <formula>

export HOMEBREW_NO_EMOJI=1
This sets the HOMEBREW_NO_EMOJI environment variable, causing Homebrew to hide all emoji.
The beer emoji can also be replaced with other character(s):
export HOMEBREW_INSTALL_BADGE="☕️ 🐸"
In Sublime Text 2/3, you can use Package Control to install Homebrew-formula-syntax, which adds highlighting for inline patches.
brew.vim adds highlighting to inline patches in Vim.
homebrew-mode provides syntax highlighting for inline patches as well as a number of helper functions for editing formula files.
pcmpl-homebrew provides completion for emacs shell-mode and eshell-mode.
language-homebrew-formula adds highlighting and diff support (with the language-diff plugin).
