Running the production server locally gives me: 在本地运行生产服务器可以使我：
Missing secret_key_base for 'production' environment, set this value in config/secrets.yml 在“生产”环境中缺少secret_key_base ，请在config/secrets.yml secret_key_base中设置此值
I've added secrets.yml to Git but still no luck. 我向Git中添加了secrets.yml，但还是没有运气。

Try running your production code locally to see if you can replicate the error. 尝试在本地运行生产代码，以查看是否可以复制该错误。 Type this into your terminal/console: 在您的终端/控制台中输入以下内容：
RAILS_ENV=production rails server
If you don't see the same error on production locally, then I'd guess it's a Heroku-specific error. 如果您在本地生产中没有看到相同的错误，那么我想这是特定于Heroku的错误。

I rebuilt the application and now it works fine. 我重建了应用程序，现在可以正常工作了。 I was unable to understand what the exact problem was but I believe it was due to case sensitivity. 我无法理解确切的问题是什么，但是我认为这是由于区分大小写所致。 I might have created a controller with a lowercase letter. 我可能用小写字母创建了一个控制器。 As Ruby is case insensitive but Heroku is I believe Heroku was unable to GET the path. 由于Ruby不区分大小写，但Heroku相信Heroku无法获取路径。

Heroku reads the secret from an ENV variable, not secrets.yml. Heroku从ENV变量而不是secrets.yml中读取机密。
