わかりました、完了しました。なぜこのエラーが発生したのか理解できません:

rake features

mysqlに接続できないのは、次の原因ではありません。

rake db:migrate

完璧に動作します。

このエラーが発生し続けます：

DB を保存し、mysql を再インストールします。http://hivelogic.com/articles/compiling-mysql-on-snow-leopard/に従ってください。すべての問題が解消されました。

私はあなたの問題について理論を立てる必要がありますが、どちらも本当にあなたの原因であると疑う理由はありませんが、それらは簡単なチェックです.

  1. でテスト データベースを適切に定義していません。config/databases.yml

  2. このデータベースを構築しようとしている mysql ユーザーには、そのための権限がありません。

次の出力を教えてください：

rake db:schema:load RAILS_ENV=test

_test という名前の既存のデータベースが構成され、config/database.yml で動作していることを確認します。

問題の資格情報 (database.yml 内のすべてのもの) を使用して問題のデータベースに接続できますか?
コマンドラインから「mysql -u your_user -p」？

mysql gem をインストールしたときに、ネイティブ拡張機能が適切にビルドされましたか? gem install mysql --force (再インストールするため) を実行するとどうなりますか? 幸せそうに見えますか？

これまでにこれを行ったことがありますか？問題は、rails/mysql またはその両方の経験不足である可能性が高いですか? それとも、この古い帽子で、今回はわからないのですか？

前者の場合、レールを使用した実用的なアジャイル Web 開発のチュートリアルは非常に優れています (本の残りの部分と同様)。

そこに何か役立つことを願っています。
