Ruby on rails Heroku启动应用程序错误Ruby on Rails

正在尝试在Heroku上启动应用程序，但它不断收到应用程序错误。这是heroku日志，请让我知道我能做些什么来让应用程序运行。我们已经实现了pusher，可以让网站在本地主机上运行，甚至可以跨不同的本地主机运行pusher功能，但除此之外，它在heroku上不起作用

正如您所提到的，在本地主机上正常工作时不会出现此错误。尝试删除或注释CommentsController调用，并检查是否能够在Heroku上部署应用程序？一旦应用程序运行，您就可以启用并检查导致此错误的真正原因。

有人试图向/comments发送邮件，而您尚未在CommentsController上定义创建方法。如果您实现了该方法呢？到目前为止，您使用Heroku工具箱完成了哪些步骤？这不是传入的请求-加载CommentsController类是个问题。我认为第2行包含一个post呼叫-可能是路线定义放错了位置？app/controllers/comments\u controller.rb的内容是什么？
