奇怪的是，一切都在控制台中工作

为什么使用rspec而不是rails会发生这种情况？我该如何修复它

我正在使用

轨道（4.0.4）
rspec（2.14.1）

rspec没有自动加载

应用程序/workers

路径，因为它不是标准的rails布局，您可以将自动加载行添加到spec\u帮助程序中，或者直接要求spec中的文件

正如jfornoff所建议的，您可以向规范中添加一条require语句，其语句如下所示：

需要“app/workers/station/http”

但是，如果您使用的是SpringRails应用程序预加载程序，而上述方法无法解决问题，那么您还可以检查Spring是否需要重新启动。您可以在不使用Spring的情况下测试运行规范，如下所示：

bundle exec rspec spec/workers/station/http_spec.rb

module Worker
  module Station
    class HTTP
      # ...
    end
  end
end

describe Worker::Station::HTTP do
  it "should do something"  do
  end 
end

。。。或者

spring stop # or bin/spring stop
rspec spec/workers/station/http_spec.rb

注意：如果上面/下面的解决方案不适用于您。

在Rails4.1和4.2中，我在尝试运行以下命令时遇到了类似的错误

$ spring rspec spec/classes/email_parser/email_provider_spec.rb:163

甚至试过

$ rspec spec/classes/email_parser/email_provider_spec.rb:163

无法自动加载常量帐户：：正在加载

我也犯了同样的错误。你知道如何解决这个问题了吗？rspec没有自动加载应用程序/工作者路径，因为它不是标准的rails布局，你可以将自动加载行添加到spec_帮助程序中，或者直接要求spec中的文件@jfornoff请插入您的评论作为回答。这将帮助其他遇到此问题的ppl。谢谢你的帮助！说得好，谢谢
