How to completely remove Rspec and its generated files, and reinstall them into a project?

Question

Is it possible to completely remove rspec from a project, and then reinstall it again?

The reason I ask is because I had started my project on Rails 3 beta, and now that the new one has come out, the new rspec conflicts and nothing passes. But if I start a new project, everything seems to work as expected.

Answer 1

So its not rspec that needs to be removed like Nathanvda recommended in his comment, but HAML does need to be removed in Rails 3. Instead I used the haml-rails gem, and uninstalled all older version of haml. Works like a gem now. :D

Then what I did was deleted all the specs that were created for my other scaffolds, and regenerated them.
