RSpec: Could not find generator rspec:install

I installed latest Rspec gem and dependences, but when I call script/rails generate rspec:install, I get this error: Could not find generator rspec:install.

Whats wrong?

Upgrade to Bundler 1.0.9: gem install bundler

It was released on 1/19/2011 and fixes a bug where any gems included in :development, :test, etc. groups weren't loaded properly in rails.

Try to run it like this

rails g rspec:install RAILS_ENV="test"
