黃瓜工作正常沒有spork，但spork給我「未初始化常量黃瓜::導軌」

Question

我已經有rspecs和黃瓜功能都運行良好。

我正在安裝spork（spork-rails實際上）給我一些重新運行加速。

我已經使用spork正常運行rspec。

我剛剛按照說明修改了env.rb（非常類似於spec_helper.rb的mod），但是當我嘗試運行bundle exec cucubmer --drb時，我得到了uninitialized constant Cucumber::Rails。

的Rails 3.2的方式

任何想法？

這裏是我的env.rb：

require 'rubygems' 
require 'spork' 
#uncomment the following line to use spork with the debugger 
require 'spork/ext/ruby-debug' 


if Spork.using_spork? 
    Spork.prefork do 

    require 'rails' 
    require 'cucumber/rails' 

    Capybara.default_selector = :css 

    begin 
     DatabaseCleaner.strategy = :transaction 
    rescue NameError 
     raise "You need to add database_cleaner to your Gemfile (in the :test group) if you wish to use it." 
    end  

    end 

    Spork.each_run do 
    # This code will be run each time you run your specs. 
    require 'cucumber/rails' 
    Cucumber::Rails::Database.javascript_strategy = :truncation 

    ActionController::Base.allow_rescue = false 


    module NavigationHelpers 
     def path_to(page_name) 
     case page_name 

     when /the home page/ 
      root_path 
     # Add more page name => path mappings here 
     else 
      if path = match_rails_path_for(page_name) 
      path 
      else 
      raise "Can't find mapping from \"#{page_name}\" to a path.\n" + 
      "Now, go and add a mapping in features/support/paths.rb" 
      end 
     end 
     end 

     def match_rails_path_for(page_name) 
     if page_name.match(/the (.*) page/) 
      return send "#{$1.gsub(" ", "_")}_path" rescue nil 
     end 
     end 
    end 

    World(NavigationHelpers) 
    end 
else 

    #omitted 
end

以供將來參考記下我做了什麼來解決這個問題。最後，我認爲這是在Gemfile中稍微錯誤地引用了黃瓜欄的奇怪症狀。

我得到的錯誤以及話說：

WARNING: Cucumber-rails required outside of env.rb. 
The rest of loading is being defered until env.rb is called. 
To avoid this warning, move 'gem cucumber-rails' under only 
group :test in your Gemfile 

繼https://github.com/cucumber/cucumber/issues/249的說明，我通過增加固定此要求：假到我的Gemfile如下：

group :test do 
    gem 'cucumber-rails', require:false 
    #.... 
end
