Working version of Homebrew for OS X 10.10

The only way to get working Homebrew on OS X 10.10 for now (10.10 beta was just released a couple of hours ago) is by using an special fork by @jacknagel available at https://github.com/jacknagel/homebrew/tree/rb2.

To install this working version of Homebrew just execute:

ruby -e "$(curl -fsSL https://gist.githubusercontent.com/jpincheira/bd3698fee46735fac252/raw/2c6a2f81927871c1a64e2dfbbc5eef451c71a9ac/homebrew.rb)"

homebrew.rb

# This script installs to /usr/local only. To install elsewhere you can just
# untar https://github.com/jacknagel/homebrew/tarball/rb2 anywhere you like or
# change the value of HOMEBREW_PREFIX.
HOMEBREW_PREFIX = '/usr/local'
HOMEBREW_CACHE = '/Library/Caches/Homebrew'

@zaur and @danscan Try installing the command line tools:

That branch appears to have been removed. Is there another solution?

It worked for me. Anyway, there is already official fix Homebrew/legacy-homebrew#29795

The command in the gist is not working for me:

==> Downloading and installing Homebrew...
fatal: Couldn't find remote ref rb2
Unexpected end of command stream
Failed during: git fetch origin rb2:refs/remotes/origin/rb2 -n

Is rb2 branch still there?

Same here.

Never mind. It seems the core install works on 10.10. Although brew doctor command keeps failing. Does not seem to be a show stopper so far

Homebrew has been updated to use the Current Ruby version, so a simple git pull will probably suffice:

cd /usr/local && git pull origin master

I get :
error: Untracked working tree file '.gitignore' would be overwritten by merge.

I'm getting this error when doing the pull.. Any ideas?
➜ local git:(master) git pull origin master /Applications/Xcode.app/Contents/Developer/usr/libexec/git-core/git-pull: line 11: git-sh-setup: No such file or directory ➜ local git:(master)

@iesta Maybe try doing git checkout -- .gitignore first?

I get the same error

fatal: Couldn't find remote ref rb2
Unexpected end of command stream
Failed during: git fetch origin rb2:refs/remotes/origin/rb2 -n

How should I go about fixing this?

Same error here

Thanks for posting an update @Spharian 👍

I worked around this issue by updating brew with git instead of my broken brew command:

cd /usr/local/Library/
git branch --set-upstream-to=origin/master master
# on branch master
git pull

Working fix: http://www.mseri.me/fix-hombrew-on-os-x-yosemite/ seems down ?

@koenpunt
Thanks, that worked:

cd /usr/local && git pull origin master
