Rake RSpec Tasks are not showing up

I have an inherited app, running on Rails 3 in Ruby 1.9, and its working fine, but for some reason, when I installed both rspec and jasmine, neither of their rake tasks are showing up when I run rake -T. The Rakefile for the app is just the standard one, and in fact, when I installed Cucumber, its rake tasks show up just fine.

If I type in rake spec, there is no error, but none of my specs are run. But, if 开发者_C百科I type rspec spec, they all run, just fine. the jasmine tasks error out, saying there is no such tasks.

Any idea why these wouldn't be showing up, but other tasks would?

Do you have rspec-rails in the development group?
