私はRubyonRailsの初心者であり、アプリにサインインする方法としてFacebookとTwitterを使用してomniauth-deviseシステムをセットアップしたいと考えています。今、私はそれを実行しようとしているところ（私は思う）にかなり近づいています。ただし、次のエラーが発生します。
ルーティングエラー
初期化されていない定数AuthServicesController
利用可能なルートの詳細については、レーキルートを実行してみてください。
そして、私はlogginを続けることができません。
私はネット上で多くの調査を行ってきましたが、同じまたは同様の問題を抱えている人を見つけることができません。
誰かが私のことを知っていますか？私はすぐに完全に迷子になります。
どうもありがとう！
ちなみに、Services_controller.rbで取得したコードはすべて次のとおりです。
