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 brokenbrew
. - Why
pbcopy
andpbpaste
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 somerm
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?
please make a proper uninstall
This is awful, and doesn't work.
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?
I dot I remove a broken brew ?

hi guys:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"
so easy!
thanks jacknagel , that worked for me
the post from self-creative worked for me. sorry to necro a dead thread but i felt that needed to be said.
Thanks self-creative!
Thanks self-creative! Home brew managed to delete a project with my .git when I tried to commit. It installed poorly and reading through this thread was daunting. Glad I read to the bottom.
Thanks, @self-creative! You saved my time a lot.
For me this command worked! 🍺
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/uninstall.sh)"
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.
