no implicit conversion of nil into String (TypeError)

Hi
I am trying to learn smashing and i got a bunch of errors. I solved them all, but now i don't know how to solve this one.

Thanks

I had the same problem today. It seems to be related to this issue: oneclick/rubyinstaller2#96
Executing gem uninstall eventmachine followed by gem install eventmachine --platform ruby seems to fix it.
