Q&A
rail s をしてサーバーを起動しようとしたら、以下のようなエラーが出ました。
エラー文を見るとUserモデルにdevise :omniauthableを加えたらなんとかなりそうですが、これはfacebook ログインを入れようとして、omniauth gemを追加し、途中でやめた為に出たエラーであると思われます。（違ったらごめんなさい）
色々あって、実装を途中でやめ、（gemを追加しただけ）その後gem uninstallで削除したはずなのですが、以下のエラーを見るに、まだしっかり削除されていないということなのでしょうか？
gemを綺麗に削除することができれば解決するとおもうのですが、やり方をおしえていただけると幸いです

エラーメッセージは routes.rb で出ているのでその中に device_for というのが残っていませんか？
また、gemをアンインストールしたとのことですが、Gemfileや Gemfile.lock からもomniauthが削除されているでしょうか？railsはGemfileから利用するgemを判断するので、こちらから消さない限り、bundle installでまた入ってしまいます。
もし残っているようでしたら、Gemfileから削除してから bundle updateをしてみてください。
