AirFlow：SQLAlchemy_Database_URIもSQLALCHEMY_BINDSも設定されていません

SQL_ALCHEMY_CONNのPOSTGRESSQLでバックアップしたローカルMACにAirFlow 2.0を設定しました。私のDagはSQLAデータベースで罰金を維持していますが、どのようなエアフローユーザーもロールテーブル/ビューが作成されていないエラーのコマンドエラーです。

Airflow ResetDBの設定とリセットを試みましたが、これらのテーブルはまだSQL_ALCHEMY_CONN DBでは使用できません。

これらのテーブルをバックエンドでどこかに作成する必要があることを期待しています。 Airflow Usersコマンドを使用しているスクリプトを介してユーザーの作成を自動化したいが、既存のエラーで、神は私を救う:)
