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

At the risk of oversimplifying things, try running

gem install bundler

I was transitioning my Ruby environment from RBENV to RVM and it worked for me.
