Railsサーバーが "no such file or directory"を実行中にクラッシュする

Question

最近githubリポジトリをクローンしました。私はそれを私のMacで動作させようとしています。私はそれをクローンし、バンドルをインストールして、すべての宝石をインストールしました。 「レールサーバー」を実行しようとすると、エラーが表示されます。

この問題を解決するにはどうすればよいですか？私は問題であるdatabase.ymlを持っていません。しかし、私はそれを複製したときにレポもしませんでした。最初にそこにいるとは思わなかったファイルを探しているのはなぜですか？

Answer 1

githubでリポジトリをプッシュすると、そのリポジトリから設定ファイルが除外されます。アプリケーションを動作させるためには、database.ymlファイルを作成する必要があります。

これはその例です。

development: 
    adapter: mysql 
    database: bibapp_development 
    username: root 
    password: 

test: 
    adapter: mysql 
    database: bibapp_test 
    username: root 
    password: 

production: 
    adapter: mysql 
    database: bibapp_production 
    username: root 
    password:
