スタックオーバーフローとウェブ全体を検索し、さまざまな修正を試みましたが、それでもherokuでレールアプリを実行できません。「申し訳ありませんが、問題が発生しました」というメッセージが頻繁に届きます。ヒロクからのエラー。
アプリはローカル環境で正常に動作します。
私は次のことをしました：
- 「heroku rake run db:migrate」を実行します
- アセットが正しくコンパイルされていることを確認しました: https://devcenter.heroku.com/articles/rails3x-asset-pipeline-cedar
- ここで参照されているように、シンサーバーを実装し、procfile を作成しました: https://devcenter.heroku.com/articles/rails3
heroku ログ ファイル (下記) を分析して、このエラーの原因を突き止めていただければ幸いです。
私のアプリはRails 3.2.7、Ruby 1.9.3で実行されており、データベースとしてpostgresを使用しています
