Rails Console and other parts are not working?

Hi, to get the project up to speed. I downloaded your project and trashed my old one. When I tried running t.approve!, i get this error (below). // also a lot of things aren't working properly for me ever. Is it because I just downloaded your project or is it because of my gemset ? Or the compability of my rails and gems. ( currently using ruby 2.2.0p0 (2014-12-25 revision 49005) [x86_64-darwin14]
