Rails/Heroku应用程序错误

Question

我试图将我的Rails应用程序部署到Heroku。到目前为止，我所做的所有工作都是创建rails应用程序，安装捆绑包并将其提交给bitbucket。下一步是部署到Heroku并打印Hello World以确认其工作。我得到这个错误：

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. 

我试图寻找一个类似的错误，但我找不到任何具体到我的问题。这里是英雄日志：

我删除了日志的日期和时间，所以它更容易阅读，行不那么宽。我也明显的原因删除了我的电子邮件/帐户。

Answer 1

通过查看日志，似乎有什么fog gem导致启动rails服务器的问题。

正如你所说，你只是想测试“你好世界”，我会建议暂时请从Gemfile remove fog gem并重新部署在heroku上。

如果一切正常，那么以后你总是可以调试雾问题。

Answer 2

这里的错误：

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

看起来你一直在努力，包括某种ssh功能集成到你的应用程序？

具体来说，它看起来像它来自fog宝石。

根据以下question，你应该能够要么fog或net-ssh宝石添加到您的应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，然后推到Heroku的。

在黑暗中刺伤;如果它不起作用，我会很乐意删除这个答案。
