我推送了我的最新代码，然后我的 heroku 应用程序停止工作。我检查了日志并收到一条错误消息。是否有我应该移除的特定宝石？这是数据库错误吗？

我运行了 heroku run rake db:migrate 以防万一出现问题并得到类似的警告：

是否有我应该移除的特定宝石？

这里发生了两件事：弃用警告和错误。错误是

/app/app/controllers/admin/users_controller.rb:1:in `<top (required)>': superclass mismatch for class UsersController (TypeError)

superclass mismatch for class UsersController这通常意味着您使用的名称已被使用。我的第一个猜测是您的管理文件夹和根控制器文件夹中有一个 UsersController，但这只是一个猜测。无论哪种方式，您在调用超类时都会在某处出错。

弃用警告不应该引起任何问题，只是警告为将来的 Rails 版本更改该代码。
