I've got some problems with this package manager. I can't find how to remove it!

Is it safe to remove whole /usr/local? Homebrew was installed somewhere in that directory.

Homebrew recommends a script, also linked in their FAQ.

cd `brew --prefix`
git checkout master
git ls-files -z | pbcopy
rm -rf Cellar
bin/brew prune
pbpaste | xargs -0 rm
rm -r Library/Homebrew Library/Aliases Library/Formula Library/Contributions 
test -d Library/LinkedKegs && rm -r Library/LinkedKegs
rmdir -p bin Library share/man/man1 2> /dev/null
rm -rf .git
rm -rf ~/Library/Caches/Homebrew
rm -rf ~/Library/Logs/Homebrew
rm -rf /Library/Caches/Homebrew

This should also revert your /usr/local folder to its pre-Homebrew days. See the Homebrew installation wiki for more information.

Note: You may also need to remove ~/.homebrew as well. If you happen to have ~/.rvm, then you should delete ~/.rvm/bin/brew.

thank you so much! i've googled so hard, but even't bothered to look for uninstallation actions in installation manual! ;D –  holms Oct 28 '10 at 15:36

Note that the instructions have changed over time, and also been moved to the Homebrew FAQ github.com/mxcl/homebrew/wiki/FAQ/… –  Nelson Sep 10 '11 at 23:19

Following these commands deleted almost all my files on Desktop, Documents and 'Downloads`. It messed up my git too. Please help! –  Ava Aug 16 '13 at 22:53

Also note that homebrew changes group to 'staff' and gives write access to group for

  • /usr/local
  • /usr/local/bin
  • /usr/local/include
  • /usr/local/lib
  • /usr/local/sbin
  • /usr/local/share

In order to put back these directories in their original states do:

sudo chown root:wheel <directory> ; sudo chmod 755 <directory>

for each one or if you don't have fancy owners / rights:

sudo chown -R root:wheel /usr/local ; sudo chmod -R 755 /usr/local

I cannot confirm this. My /usr/local and its Homebrew-created subdirs are owned by my user with the admin group. –  slhck Dec 26 '12 at 16:21

Try this gist, it uninstalls homebrew and associated caches, provided you installed brew to the default directory.

There might be other files in /usr/local you might need you might be able to user a different PM to remove the current PM.

I'm unclear as to what this answer means. What's a PM? –  echristopherson May 16 '13 at 4:00

I recently made a script to handle this case - it completely removes Homebrew, and has CLI options like silent/verbose and force modes, as well as mode that returns the location of your Homebrew installation: https://gist.github.com/SteveBenner/11254428
