Rails/Heroku應用程序錯誤

Question

我試圖將我的Rails應用程序部署到Heroku。到目前爲止，我所做的所有工作都是創建rails應用程序，安裝捆綁包並將其提交給bitbucket。下一步是部署到Heroku並打印Hello World以確認其工作。我得到這個錯誤：

Application Error 
An error occurred in the application and your page could not be served. Please try again in a few moments. 

If you are the application owner, check your logs for details. 

我試圖尋找一個類似的錯誤，但我找不到任何具體到我的問題。這裏是英雄日誌：

我刪除了日誌的日期和時間，所以它更容易閱讀，行不那麼寬。我也明顯的原因刪除了我的電子郵件/帳戶。

Answer 1

通過查看日誌，似乎有什麼fog gem導致啓動rails服務器的問題。

正如你所說，你只是想測試「你好世界」，我會建議暫時請從Gemfile remove fog gem並重新部署在heroku上。

如果一切正常，那麼以後你總是可以調試霧問題。

Answer 2

這裏的錯誤：

'require': cannot load such file -- net/ssh (LoadError)

看起來你一直在努力，包括某種ssh功能集成到你的應用程序？

具體來說，它看起來像它來自fog寶石。

根據以下question，你應該能夠要麼fog或net-ssh寶石添加到您的應用程序得到它的工作：

#Gemfile 
gem 'fog', '~> 1.36.0' 
gem 'net-ssh' 

添加那些在本地，然後推到Heroku的。

在黑暗中刺傷;如果它不起作用，我會很樂意刪除這個答案。
