When I run
rails server
I get the error.
There is some problem loading the gemsets
$rvm list rvm rubies ruby-1.9.
I'd recommend using a .ruby-version file in the top-level directory of your project. That file would contain containing the ruby version spec'd in your Gemfile, e.g.
.ruby-version
Gemfile
2.1.0
That apparently is the cross-{rbenv,rvm} way of spec'ing the version now.
{rbenv,rvm}
