I'm having trouble with Ruby on OS X Mavericks... I think I may have overstepped and tried to install too many versions... I can get the CMD prompt. I can do rvm use 2.0.0 command. But when I try and start the server I dont get anything like the output that was given in the video... I get..
Charles-Franklins-iMac:~ charlesfranklin$ rails server
/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/dependency.rb:296:in to_specs': Could not find 'railties' (>= 0) among 6 total gem(s) (Gem::LoadError)

If anyone can help I'd appreciate it...
