I’m trying to get Rspec working. Using the installing 1.0.7 & the Rails  
plugin, I tried one of the examples on Rspec’s website and produced the  
following error:

############################################################################  
Your RSpec on Rails plugin is incompatible with your installed RSpec.

RSpec : 1.0.7 (r2332)  
RSpec on Rails : r2331

Make sure your RSpec on Rails plugin is compatible with your RSpec gem.  
See [http://rspec.rubyforge.org/documentation/rails/install.html](http://rspec.rubyforge.org/documentation/rails/install.html) for  
details.  
############################################################################

I’m running Windows XP. Is there a way to roll RSpec back to r2331?

Try checking out the trunk version of the rspec and the rails plugins  
(see [http://rspec.rubyforge.org/documentation/rails/install.html](http://rspec.rubyforge.org/documentation/rails/install.html)  
under “Living on the Edge”). That way you are certain to have  
matching version tags. BTW: A good resource is rspec-

Happy spec’ing.

The 1.0.7 release suffered a deployment problem and is already  
replaced by 1.0.8.

Go ahead and give that a shot.
