私のGoogle-fooがこの問題についてかなり弱かったです。誰も助けることができますか？

Answer 1

最近、Rails 4で秘密のCookieストアが削除されました。Changelogを参照してください。

アプリを再び動作させるには、config/initializers/session_store.rbのconfig.session_store :encrypted_cookie_store行をconfig.session_store :cookie_storeに置き換えます。ストアは自動的に暗号化されます。

もしわからない場合は、新しいRails 4アプリ（rails new app_name --pre）を作成し、イニシャライザを見てください。
