git clone git://github.com/rspec/rspec-rails.git cd rspec-rails gem install bundler bundle install
Now you should be able to run any of:
rake rake spec rake cucumber
Or, if you prefer to use the rspec and cucumber commands directly, you can either:
bundle exec rspec
bundle install --binstubs bin/rspec
The Gemfile includes the gems you'll need to be able to run specs. If you want to customize your dev enviroment with additional tools like guard or ruby-debug, add any additional gem declarations to Gemfile-custom (see Gemfile-custom.sample for some examples).
