黃瓜找不到安裝寶石

Question

環境/ cucumber.rb：

... 
# gem dependencies 
config.gem 'cucumber-rails', :lib => false, :version => '>=0.3.0' unless File.directory?(File.join(Rails.root, 'vend 
config.gem 'database_cleaner', :lib => false, :version => '>=0.5.0' unless File.directory?(File.join(Rails.root, 'vend

Missing these required gems: 
    selenium-client 
    Selenium 
    rspec-rails 

You're running: 
    ruby 1.9.1.378 at /home/artem/.rvm/rubies/ruby-1.9.1-p378/bin/ruby 
    rubygems 1.3.5 at /home/artem/.rvm/gems/ruby-1.9.1-p378, /home/artem/.rvm/gems/ruby-1.9.1-p378%global 

所有的寶石都顯得有：

artem:~/projects/food4feed (master)$ gem list | egrep "elenium|rspec|test-unit" 
rspec (1.3.0) 
rspec-rails (1.3.2) 
Selenium (1.1.14) 
selenium-client (1.2.18) 
test-unit (2.0.7) 

更令人困惑的是，它只是抱怨某些寶石。 factory_girl和rspec不會導致問題。

任何想法是怎麼回事？

• 黃瓜（0.6.3）
• 黃瓜導軌（0.3.0）

Answer 1

好的，我想到了（在aslakhellesoy的幫助下，謝謝！）。當黃瓜說Missing these required gems它也可能意味着Can't load these required gems。這增加了所有可能的錯誤。

在這種情況下，寶石名稱（除了rspec-rails）與要求的相應庫文件不匹配。例如，應該有:lib => 'selenium'添加到config.gem 'selenium-client'。

至於rspec-rails，由於測試單元版本錯誤導致無法加載：Gem::LoadError: RubyGem version error: test-unit(2.0.7 not = 1.2.3)。如果黃瓜首先報告了這個錯誤（我從需要從控制檯請求rspec-rails），它會有很大的幫助。

Answer 2

你有需要'test-unit'在config/environment.rb或features/support/env.rb文件中的某處？

如果你這樣做，那是錯誤的。測試單元gem沒有test-unit.rb文件，因此要求'test-unit'將始終失敗。儘量去除需要對線路，或者至少嘗試需要正確的文件：

請求「test /單元」

我不知道爲什麼你想無論如何要明確負載測試單元。
