Django Webサイトにgunicornをインストールして使用しようとしましたが、次のエラーが発生します。

同様のエラーがあるこの質問を見つけましたが、内部のDATABASESdictsettings.pyは正しいようです：

DATABASES = {
    'default': {
        'ENGINE': 'postgresql_psycopg2',
        ...
    }
}

私は自分のに入れgunicornましたINSTALLED_APPS。runserverうまく動作します。southそれ自体でもうまくいくようです。

コメントアウトすることで、gunicornを機能させることができましsouthたINSTALLED_APPS。これは、本番環境にデプロイするときにできると思います。何が起こっている？

（その価値のために、私はDjango 1.3.2を使用しています）

データベース バックエンドのフル パスを使用してみてください。

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        ...
    }
}
