カピストラーノを使用して、既存の ROR アプリケーションにいくつかの変更をデプロイしようとしています。MAC OSX を実行しており、サーバーは Ubuntu 12.0.4 です。私は ROR と capistrano を初めて使用するので、これまでに行ったことの概要を以下に示します。github リポジトリをローカル フォルダーに複製し、コードを変更し、github リポジトリを更新し、次を使用して capistrano をインストールしました: を使用してgem install capistrano、ターミナルを開き、ディレクトリを ROR アプリがあるローカル フォルダーに変更し、 を試しcap deploy:checkました。プロジェクトには既存の Deploy および Cap ファイルがあるため、プロジェクトをキャプションしませんでした。実行するcap deploy:checkと、次の出力が得られます。

これが私の deploy.rb ファイルのサンプルです (ユーザー名、サーバー名などを編集したもの)。

これについて何か助けていただければ幸いです。実稼働環境にいくつかの変更をデプロイする必要があるだけですが、今はまだ立ち往生しています。うまくいけば、私は十分な情報を提供しました。ただし、cap と ruby にまったく慣れていないので、明らかなことを見落としている可能性があります。前もって感謝します！
