Rails 4 Heroku 部署页面不存在

Question

我有一个基本的 rails 应用程序，只包含欢迎控制器和索引操作。它们都是空的。我已经定义了一个根路由到它。并部署到 heroku。但我得到“你正在寻找的页面不存在。”此错误消息。我的网址是 "https://murmuring-island-27368.herokuapp. c o m/"。（请从 c o m 中删除空格）。顺便说一句，我尝试在本地运行生产环境，但它显示“内部服务器错误

“生产”环境缺少secret_token 和secret_key_base，请在config/secrets.yml"中设置这些值。那我该怎么办？

这是 gem 文件。
