I had the same problem yesterday, when I upgraded all my gems. It turns out,
this error occurs if you have one broken gem.
My solution: Add a puts statement inside gem_path_searcher.rb to find out
what gem is broken. Then uninstall it. (For me it was the latest
mojombo-grit).

A better solution would be to patch Rubygems so it doesn't choke just
because you have a broken gem - or at least tell you which one it is.
