Cannot install Cocoapods into app when typing "pod install" (ERROR: Failed to build gem native extension.)

I am using OSX Yoemite and I have visited almost all questions about this on StackOverflow and none of the answers worked... I am currently trying to use the command "pod install" and I am getting this error:

And it also says: ERROR: Failed to build gem native extension. Does anyone know how to fix this? Thanks!
