mysql + ruby​​ =悪夢

了解しました。 私はこのエラーを受け取った理由を理解できません:

rake features

mysqlに接続できないことが原因ではありません。

rake db:migrate

完璧に動作します。

私はこのエラーが発生し続けます:

私はあなたの問題について理論を立てなければなりませんが、疑う理由は実際にはあなたの原因ではありませんが、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ない 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、 そうする許可。

問題の資格情報(database.yml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の「mysql -u your_user -p」

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

これをやったことがありますか? 問題はrails / mysqlまたは両方の経験の不足である可能性が高いですか? それとも、この古い帽子であり、あなたは今回それを理解することができませんか?

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(本の残りの部分も同様です)。

そこに何かが役立つことを願っています。

次の出力を教えてください:

レーキdb:schema:load RAILS_ENV = test

_testという名前の既存のデータベースが設定され、config / database.ymlの下で動作していることを確認する
