Rails アプリを Ubuntu 11.10 サーバーで実行する方法を教えてください。
約 2 日間使用していますが、ここのスクリーン ショットに示されている部分を通過できません。私が知る限り、rvm、レール、ルビー、カピストラーノ、フュージョンパッセンジャーはすべて正しくインストールされています。私が抱えている問題は、データベース（mysql）またはデータベースと通信するためのレールの取得に関係していると思います（以下のエラーメッセージから推測しています）。
Error message:
undefined method `active_record' for #<Rails::Application::Configuration:0x00000002e43fe8>
Exception class:
NoMethodError
Application root:
/var/www/jamesbay/blog/current
私の主な質問は、これをデバッグするにはどうすればよいですか? リストにある config.ru ファイル、application.rb、および environment.rb を変更しようとしましたが、解決策はありません。これらのエラーが何を意味するのか完全にはわかりません!
サーバー上のディレクトリにカピストラーノを適切にデプロイしています。git リポジトリを更新し、さまざまな「cap」コマンドを使用して、ローカル マシンからサーバーへの実際の展開を処理できます。
どんな助けでも大歓迎です！(私はレールを約 2 週間しか使用していませんが、このプロジェクトのおかげで、サーバー管理について TON を既に学んでいます)
