If you upgraded to OSX 10.10 Yosemite, and now have a broken homebrew, fear not
- the homebrew team has already fixed this!
Luckily, the steps to fix it are fairly simple.
First, update homebrew via
cd /usr/local/Library git pull origin master
Next, use homebrew to update and clean your installed packages:
brew update brew prune brew doctor
Now you should be all set!
I originally found (and tweeted about) this article when searching for a fix, but ran into more issues after editing the
brew.rb file, and eventually came to the solution of updating homebrew itself after seeing that the homebrew team had fixed the issue themselves.
