`<top (requ ired)>' bin/rails:4:in `require' bin/rails:4:in `<main>' i know error occurs changing gemfile because works before change it. want follow michael closely possible. different i'm using ruby 1.9.3 , using ruby 2.0, though in book said if not using 2 change in gemfile did.
you declaring ruby '2.0.0' @ begin of gemfile using 1.9.3 fail when trying detect it. change ruby '1.9.3'
also might need run bundle in order install gems.
