要求：沒有這樣的文件加載 - test_helper（LoadError）只在生產中發生而不在開發中

Question

我是Ruby on Rails的新手和遵循Michael Hartl的Ruby On Rails教程。我在第9章，一切正常，開發 - 所有測試都通過了，我可以打開並移動應用程序。但是，當我嘗試打開生產（Heroku）時，應用程序崩潰。這裏是Heroku的控制檯錯誤信息：如果我嘗試

rails s -e production 

我已經證實我的test_helper.rb中的文件確實是在我的測試文件夾

我得到了同樣的信息。任何幫助讚賞。

Answer 1

這是在黑暗中刺，但你是否要求你的應用程序中的其他地方test_helper？從閱讀回溯看起來你需要在app/app/helpers/sessions_helper_test.rb。

此外，app/app/看起來很腥。你的應用程序文件夾內是否有應用程序文件夾？這可能也是一個問題。
