title: `to_specs': Could not find 'railties' (>= 0) among 8 total gem(s) (Gem::LoadError)
body: <p>I postes this question because I didn't find any related answer on stackoverflow. I did everything. I will explain what I have tried.
  When I start the Rails server using <code>rails s</code>, I get the following output:</p>
