Getting a “bad interpreter” error when using brew

Question

I\'m getting this error when I try to run any brew command.

Holger-Sindbaeks-MacBook-Air:~ holgersindbaek$ brew help
-bash: /usr/local/bin/brew: /usr/bin/rub         


        

Answer 1

This happened because I needed to update brew - in the updated version it already uses Current ruby

cd /usr/local
git pull -q origin refs/heads/master:refs/remotes/origin/master

This solved the problem
