Ruby on Rails

If you use Rails < 3.0 version, so its version is defined in your_app/
config/environment.rb file as

RAILS_GEM_VERSION = '2.3.8' unless defined? RAILS_GEM_VERSION

To get your RoR application running on a dedicated host, you should
have the same Rails and gem versions on the server that you use in the
development environment. If not you risk to have some compatibility
problems, weird messages, etc.
Rails 3 uses a little bit different project structure, command syntax
and a lot of other new features (see Rails 3 release notes and guides
for more information). You will find compatibility issues (Ruby
version required to use Rails 3, etc.) out there.
