我正在尝试将我的 Rails 应用程序从 ubuntu 移动到 osx。运行 rspec 时，出现以下模糊错误：

/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.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:8:in `block in autorun'

一切都在 Ubuntu 中运行良好，所以我想它一定是环境的。任何想法从哪里开始挖掘？

编辑：不知道为什么，但是 rake 找不到文件 request_helpers.rb。把它移到别处解决了这个问题。

这似乎不是操作系统问题，而是配置问题。确保您的环境在以下方面是相同的：

  • 使用 rvm 安装方式相同
  • 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。

顺便说一句，这不是一条晦涩难懂的信息，实际上很清楚：

uninitialized constant RequestHelpers (NameError)

所以spec/support/devise.rb文件找不到所需的类。

你写过那个文件吗？如果没有，您是如何生成的？重复该过程以生成它（可能是rake something或rails generate something），它就可以了。
