I used the code in the gist to uninstall Homebrew with the intent of reinstalling Homebrew afterwards. The code seemed to work, but when attempting a reinstall:

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

I got the following:

/Users/joevanleeuwen/.rbenv/shims/ruby: line 21: /usr/local/Cellar/rbenv/0.4.0/libexec/rbenv: No such file or directory

I'm surprised Homebrew would promote this installation process if it is not sufficient, seeing that others have run into issues. I do not know where to go from here.

Ah, somehow my $PATH variable was messed up. For some reason was:

/Users/joevanleeuwen/.rbenv/shims:/usr/local/bin:/usr/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin

I removed /Users/joevanleeuwen/.rbenv/shims: from $PATH and was able to successfully install Homebrew after using the prompted code:

rm -rf /usr/local/Cellar /usr/local/.git && brew cleanup

i can confirm that rmdir -p bin Library share/man/man1 2> /dev/null is not compatible with set -e and that if those directories are not empty then the script will not finish leaving stuff in .git and Library. how do we go about getting this updated? cc @mxcl

I hate dealing with Bash, so I created a rigorous script in Ruby to uninstall Homebrew. It has some nice CLI options, searches a few extra locations for files based on feedback on Stack Overflow, and there is a flexible mechanism for locating Homebrew install locations.

I would love feedback on this; I tested it thorougly, but can't cover all the edge cases for more tricky things like permissions (which is why I advocate the use of sudo to run this). I actually want to contribute to trunk Homebrew at some point but don't have the time yet; I thought I'd at least pitch in my two cents here! Let's start making it easier to uninstall the best Mac package manager guys! The script is here: https://gist.github.com/SteveBenner/11254428

Oh, and I thought about changing the permissions of the original directories as part of this, but I'm on the fence. It really seems like something that should be a discrete operation, but I'll probably add the capability at some point.

Thanks! I'm switching to Mac Ports because it actually installs stuff rather than putting it into a separate directory and refusing to let me use sudo to link anything.

looks like homebrew allows you to uninstall it with this command

 rm -rf /usr/local/Cellar /usr/local/.git && brew cleanup

Is the comment proposed by dylan947 a legit way of removing homebrew? I'm holding off installing till I know there is a clean way of uninstalling.

ghost commented Aug 3, 2014

Will original script above still work and remove Homebrew completely? I am new to this but I need to know if above original uninstall instruction works.

Background if needed -
I tried installing Homebrew few days ago but terminal kept giving me different warning messages, something about some python file and some other stuff I don't know about. An instructor, in a class I am taking, uninstalled some files that were getting in a way and it we got it to install . Unfortunatly it still wouldn't work, due to what I think is a perl file. We gave up after that and I am using some gui solution. Homebrew still doesn't work and I want to get rid of it. Please help.

After running the commands here, I'm still being told that homebrew is already installed on my system, when I try to do a reinstall.

MacBook-Pro:~ Dygear$ ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"
It appears Homebrew is already installed. If your intent is to reinstall you
should do the following before running this installer again:
    rm -rf /usr/local/Cellar /usr/local/.git && brew cleanup
MacBook-Pro:~ Dygear$ 

Doing what it suggests results in this:

MacBook-Pro:~ Dygear$ rm -rf /usr/local/Cellar /usr/local/.git && brew cleanup
-bash: brew: command not found

Any ideas?

running cd brew --prefix tells me:
line 13: cd: /Library/Frameworks/Python.framework/Versions/2.7/bin/../Library: No such file or directory
/Library/Frameworks/Python.framework/Versions/2.7/bin/brew: line 23: /brew.rb: No such file or directory
/Library/Frameworks/Python.framework/Versions/2.7/bin/brew: line 23: exec: /brew.rb: cannot execute: No such file or directory

Anything i run with brew tells me the same error. If i trye to reinstall brew using:
ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

it tells me to run:
rm -rf /usr/local/Cellar /usr/local/.git && brew cleanup

which also tells me the same thing i get told when i run cd brew --prefix

Any ideas?

I am having the same problem as Dygear. Any ideas? I tried running the script and got the following:

$ /bin/sh uninstall_homebrew.sh
brew update first!

but brew update gives me:

$ brew update
-bash: brew: command not found

I tried looking for a /usr/local/Cellar but it doesn't exist.

@somnicide it's a message from the original gist/script above: there is no .git directory.

test -d /usr/local/.git || abort "brew update first!"

If you don't have /usr/local/Cellar, your hombrew installation could be already removed, except if you installed homebrew elsewhere..

This one is insanely dangerous.

  • A $(brew --prefix) with an blank in it (though it shouldn't have happened in the first place) will kill you. So will a somehow broken brew.
  • Why pbcopy and pbpaste are used instead of a command substitution & variable assignment is beyond me — system clipboard could change without notice at any time.
  • There's no git reset --hard so some rm might fail.

In general, when you do rm -rf in a script, you should be absolutely certain that every single thing you run worked as expected. Test $? everywhere (or simply wrap your commands in if ! cmd; then's.

Hello I just went through the original commands and after the command :
rmdir -p bin Library share/man/man1 2> /dev/null
I got this:
[Process completed]

I am relatively new to using Terminal and was wondering what to do next.

Thanks

@sergea29 It closed your terminal session. Just close and re-open your terminal to continue.

Thank you for the help. The original commands were copy/pasted all at once as recommended. So I was surprised it stopped. Before continuing I will input the cd command again. Is there anything else I should do?

The test -d /usr/local/.git line should probably be test -d brew --prefix/.git or similar, if it's supposed to handle Homebrew installed somewhere other than /usr/local. (Which seems like the point of the cd line.)

For anyone seeking a superior method of removing Homebrew, I highly recommend using the uninstaller script I wrote for this purpose. It is robust, safe, unobtrusive, and extremely user-friendly.

If I use the installer on /usr/local/Cellar/ will it remove all the folders? I have folders such as postgresl, python, and octave. Those I'd like to keep. Will I need to re-install after installing HomeBrew? There are other folders such s gcc, sip, etc. which I presume come with the HomeBrew installation? My reason for removing HomeBrew is that 1) I corrupted the OS on my Yosemite iMac; 2) I had to reinstall the OS; 3) installations of software with HomeBrew still point to the old (corrupt) profile. Thanks from a newbie.

Also, do I need to remove the .git directory at /usr/local/ as well? Is .git only associated with HomeBrew?
