Question

我试图将我的rails应用程序从ubuntu移动到osx。运行rspec时，我得到以下模糊错误：

/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/runner.rb:8:in `block in autorun'

一切都在Ubuntu上很好用，所以我想它一定是环保的。有什么想法可以从哪里开始挖掘？

编辑：不明白为什么，但是rake无法找到文件request_helpers.rb。把它移到其他地方解决了这个问题。

这几乎不是操作系统问题，而是配置问题。确保您的environemnt在以下方面是相同的：

使用rvm以相同的方式安装
在Gemfile中拥有所有需要的宝石
使用bundle执行rspec
使用相同版本的所有内容。

通过这种方式，这不是一个模糊的信息，事实上非常清楚：

uninitialized constant RequestHelpers (NameError)

因此spec/support/devise.rb文件无法找到所需的类。

你写过那个文件吗？如果没有，你是如何产生它的？重复此过程以生成它（可能是rake something或rails generate something），这样就可以了。
