当点击我的RoR应用程序的"使用Facebook登录"按钮时，我收到错误：
AbstractController:：ActionNotFound，位于/users/auth/facebook/recallback找不到Devise:：OmniauthCallbacksController的操作"facebook">
你能看一下代码并提出尽可能多的解决方案吗？
以下是相关文件(询问是否需要更多(：

看起来在路由中应该是users/omniauth_callbacks
devise_for :users, :controllers => { omniauth_callbacks: "users/omniauth_callbacks", registrations: 'registrations' }
希望能有所帮助！
