Ошибки при запуске rspec с защитой и рычанием

Я учусь в старшей школе, новичок в Ruby on Rails и пытаюсь разработать приложение Rails 4 с помощью TDD. Я использую Guard вместе с уведомлениями rspec, spork и рычания, но когда я запускаю Guard для запуска своих тестов, я получаю следующий вывод и никаких результатов тестов:

11 clairehuang:mezzo$ guard

Если я запускаю только rspec независимо от Guard, мои тесты работают нормально и отображают вывод:

13 clairehuang:mezzo$ rspec
/Users/clairehuang/.rvm/gems/ruby-1.9.3-p448/gems/spork-1.0.0rc4/lib/spork.rb:83: warning: assigned but unused variable - method_name_with_spork
Run options: include {:focus=>true}

Failures:

  1) Donations GET /donations should display some donations
     Failure/Error: visit donations_path
     NameError:
       undefined local variable or method `donations_path' for #<RSpec::ExampleGroups::Donations::GETDonations:0x007ffd038e5118>
     # ./spec/requests/donations_spec.rb:6:in `block (3 levels) in <top (required)>'

Deprecation Warnings:

RSpec::Core::Configuration#treat_symbols_as_metadata_keys_with_true_values= is deprecated, it is now set to true as default and setting it to false has no effect.


If you need more of the backtrace for any of these deprecations to
identify where to make the necessary changes, you can configure
`config.raise_errors_for_deprecations!`, and it will turn the
deprecation warnings into errors, giving you the full backtrace.

1 deprecation warning total

Failed examples:

rspec ./spec/requests/donations_spec.rb:5 # Donations GET /donations should display some donations

Как я могу заставить мои тесты работать с защитой? Заранее большое спасибо!
