ruby-on-rails - devise gem を追加した後のサインイン ページでのエラー

Question

以前は完全に機能していたアプリでローカルに取り組んでいます。しかし今、に接続するときにこのメッセージエラーが表示されますlocalhost。宝石を使っていますdevise-2.2.3

Creating scope :closed. Overwriting existing method MergeRequest.closed.

  Rendered layouts/_head.html.haml (26.1ms)

ないことに気づきましたlayouts/_head.html.haml。それで、誰かがそのようなエラーの起源について考えを持っていますか?

示唆されているように、完全なスタックを投稿しますが、以前に投稿したものよりも有益ではないと思います;)
