私は現在、Capistranoを使用して最初のRailsデプロイメントを試みているところですが、克服できなかった障害に遭遇しました。cap deployエラー「mkdir: cannot create directory/public'`」が発生します。

関連する詳細：

  • Railsバージョン：3.2.6
  • キャピストラーノバージョン：2.13.5
  • Dreamhostで実行
  • アセットをプリコンパイルしているので（これは問題の一部だと思います）、load 'deploy/assets'Capfileを使用しています。

私はここの指示に従いました：http ：//wiki.dreamhost.com/Capistranoの大部分、およびCapistranoに関する他の多くの記事をWebで精査しました。

出力の下部にあるPermissiondeniedエラーと、最後に失敗したシェルコマンドを確認できます。ルート上のパブリックフォルダーのように見えるものを参照するのではなく、Webフォルダー内の相対パスを期待するため、なぜそれがで何かを行おうとしているのか理解できません。mkdirコマンドの前に追加する必要のある変数参照がどこかにないように感じますが、私が読んだドキュメントのいずれもこれを示していません。/publicpublic

私が得ることができるどんな助けにも感謝します、そして前もって感謝します。

release_path自分で設定しないshared_pathでください。Capistranoにそれを自動的に理解させてください。

deploy_toただし、正しく設定する必要があります。

set :deploy_to, "/home/<user>/<domain>/<application>"

変数にも注意してください。Capistranoのset構文は、変数が置換に使用できることを意味するものではありません。"#{base_path}/"がゼロであるために問題が発生し、に評価され"/"ます。

Capistranoの構成wikiで詳細を確認してください。
