I faced an issue with my brew installation which caused a lot of ruby error popping out every time i uses Brew. Therefore i needed a way to reinstall brew.
Uninstall Brew
A quick Google search lead me to Uninstalling brew (so I can reinstall) by Eneko Alonso and he has all the instruction listed to cleanly removing your brew installation. But make sure the first one (`brew –prefix`) returns the path where homebrew was installed properly. If not, you might ending up removing stuff from your computer you did not intend to remove.
cd `brew --prefix` rm -rf Cellar brew prune rm -rf Library .git .gitignore bin/brew README.md share/man/man1/brew rm -rf ~/Library/Caches/Homebrew
Reinstalling Brew
All you have to do is fire this on your terminal
ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"
Sit back and relax until Brew is fully installed. Once its done, remember to use "brew doctor" to make sure it said the following
$ brew doctor Your system is raring to brew.
and we are good to go!
