從ubuntu遷移到osx時未初始化的常量

Question

我試圖將我的rails應用程序從ubuntu遷移到osx。當運行rspec時，我得到以下隱藏錯誤：

/Users/josh/dev/myproject/spec/support/devise.rb:3:in `block in <top (required)>': uninitialized constant RequestHelpers (NameError) 
    from /Users/josh/.rvm/gems/ruby-1.9.3-p286@myproject/gems/rspec-core-2.11.1/lib/rspec/core.rb:92:in `configure'

    from /Users/josh/.rvm/gems/ruby-1.9.3-p286@myproject/gems/rspec-core-2.11.1/lib/rspec/core/runner.rb:62:in `run' 
    from /Users/josh/.rvm/gems/ruby-1.9.3-p286@myproject/gems/rspec-core-2.11.1/lib/rspec/core/runner.rb:8:in `block in autorun' 

在Ubuntu中一切都很好，所以我想它一定是環境。任何想法從哪裏開始挖掘？

編輯：不知道爲什麼，但文件request_helpers.rb不能用耙找到。將它移到別處解決了這個問題。

這似乎不是一個操作系統問題，更重要的是配置問題。確保您的environemnt相同的方面：使用RVM

• 安裝使用捆綁使用同一版本的執行rspec的
• 其在Gemfile中
• 所有需要的寶石同樣的方式
• 一切。

通過TE的方式，這不是一個不起眼的消息，這其實很清楚：

uninitialized constant RequestHelpers (NameError)

所以spec/support/devise.rb文件無法找到所需的類。

你寫過那個文件嗎？如果不是，你是如何產生它的？重複該過程以生成它（可能是rake something或rails generate something）並且它會正常。
