Problem installing git on yosemite

[markaduffy]

Having problems installing git with homebrew on yosemite 10.10.2. Tried every past solution available. I do have write permissions on /usr/local. I can do brew update and brew doctor with no issues, but it says I have git-git (whatever that is) already installed. I have oh-my-zsh shell. i have xcode with git and atom installed if that may be relevant. I tried using bash shell, and got same issue.

So you know the whole picture, i reinstalled git successfully from the git website, and it worked again from bash. I had to add the following path in .zshrc which was /usr/local/git/bin.

What's the result of ls /usr/local/Cellar? And can you try brew prune?

[markaduffy]

# user at mymac in ~/dev/myhubot on git:master o [13:50:22]
$ ls /usr/local/Cellar

# user at mymac in ~/dev/myhubot on git:master o [13:55:35]
$ brew prune
Pruned 0 dead formulae

Take a look at the resolution in #37250, this looks like the same issue.
