The command is only for use when creating a new project. It still works this way even if you have Rails 3 installed. You will get an error if the version of Rails specified hasn't been installed as a gem.

If you're using Ruby newer than 1.8.6 you might also get an error like this:

undefined method `camelize' for "app":String

Typically this is solved by fixing iconv: instructions for doing this when using rvm can be found here.

Post your error message and that might give a clue as to what's going wrong for you.

To change the Rails version of an existing project is a more involved process: you'd normally start by tweaking the version number in config/environment.rb (or in the app Gemfile for Rails 3) and then test and fix any errors that may occur.

This would be helpful if you could put this in some context. Just typing that at the command line after a project is created apparently does not change the rails version. I took a guess and thought you might mean to pass this as the first parameter when creating a project. Nope. I just got an error. So, would you be so kind as to put the whole command or example command in. Thanks!
