omn​​iauth facebook uninitialzed常量错误

标签： ruby-on-rails ruby omniauth-facebook

我正在关注rails cast视频here但是当我尝试运行我的服务器时，我收到错误＆＃34;未初始化的常量OmniAuth（NameError）＆＃34;。当我删除此文件时，服务器启动并显示主页，但Facebook登录验证的链接返回路由错误＆＃34;没有路由匹配[GET]＆＃34; / auth / facebook＆＃34;当然。

我的问题类似于这个stackoverlfow问题here但是我的问题处于开发模式。

所有代码都是一样的我知道这是什么。请帮忙！

此外，如果/initializers/omniauth.rb在其文件夹中，我无法生成用户模型，我需要删除它甚至这样做吗？

我安装了最新版本的omniauth-facebook gem并运行了bundle install。

你的gemfile中有omniauth和omniauth-facebook吗？像：

gem 'omniauth'
gem 'omniauth-facebook'
