i think you messed up with ruby when you updating .so possibly revert to previous commit
so what we will do is
1. revert to previous commit -- command is - "git reset -hard"
2.clean all untracked file -- command is - "git clean -d -f"
3. again update brew -- command is "brew update"

so run at terminal

[code ]
git reset --hard
[/code]

so you now back to pervious commit

as result of the above command it will checkout all file and will show where is at HEAD now
and now use git clean command to remove untracked file from the working tree 

git clean -d -f

here -d for remove whole directories
and -f for force clean

and now update brew 

brew update


Hope it work
