ruby-on-rails - 変更されていない Devise ブール値のメソッド エラーなし

Question

私はレガシー RoR アプリに取り組んでおり、(Restful_authentication プラグインの代わりとして) デバイスを構成している最中です。非常に奇妙なエラーに遭遇しました。/users/sign_inページに移動しようとすると、これが表示されます

NoMethodError in Devise::SessionsController#new

undefined method `is_navigational_format?' for #<Devise::SessionsController:0x000000034b2078>

このエラーが言及されているのを見たのは、誰かがデバイスのセッションコントローラーを独自のものでオーバーライドしようとしたときだけです。( https://groups.google.com/d/msg/plataformatec-devise/jyYNhaRztDU/MLsjwxRvf_YJ ) 私はそれを試みていません。

デバイスを正しくインストールしました（wikiに従いました）。devise_for :usersルートに追加しました。サーバーを何度も再起動しました。さらに情報や必要なファイルがあれば、喜んで提供します。

$LOAD_PATH.dup出力が含まれているレールコンソールで実行したときに編集します

"/usr/local/rvm/gems/ruby-1.9.3-p429/gems/devise-2.2.4/lib", "/usr/local/rvm/gems/ruby-1.9.3-p429/gems/devise-2.2.4/app/controllers", "/usr/local/rvm/gems/ruby-1.9.3-p429/gems/devise-2.2.4/app/helpers", "/usr/local/rvm/gems/ruby-1.9.3-p429/gems/devise-2.2.4/app/mailers" 

Rails 3.2.13、ruby 1.9.3、devise 2.2.4 を使用しています。これはフルスタック トレースです。
