I have a Rails 2.3.X project I’m working on. On my system, I have various versions of rspec, too:
rspec (2.4.0, 1.3.1)
rspec-core (2.4.0)
rspec-expectations (2.4.0)
rspec-mocks (2.4.0)
rspec-rails (2.4.1, 1.3.3, 1.3.1)
However:
> spec _1.3.1_ spec/
Missing these required gems:
rspec-rails
Install rvm and create different gemset for the wo projects. You can have seperate rvmrc for these projects.
