Why are Ruby versions conflicting when launching Rails server?

Question

I am using rbenv on OS X. When I run ruby -v, I get "ruby 2.0.0p195" but when I launch rails s I get:

Gemfile syntax error:
/myapp/Gemfile:14: syntax error, unexpected ':', expecting $end
gem "mysql2", group: :mysql

It seems that the Gemfile is processed using Ruby 1.8.7. Why is it so?

Open a new shell, and add the output of `rbenv shell 2.0.0-p195; gem env; gem list rails` to your question by appending it. Then add the output of `rbenv shell system; gem env; gem list rails`. — the Tin Man, Jul 07 '13 at 20:02

You don’t have Rails installed in your rbenv Ruby installation, so it’s falling back to the rails system binary which is hardcoded to use the system Ruby. Simply gem install rails while using your rbenv Ruby installation.
