この種のばかげた質問で申し訳ありません。私は Django の初心者です。私はDjangoの公式チュートリアルに従っていましたが、python3 manage.py syncdbの段階でこの巨大なエラーが発生しました

During handling of the above exception, another exception occurred:

The above exception was the direct cause of the following exception:

python3 、mysql ドライバーを正常にインストールしました。Ubuntu を使用しています。これが私のsettings.pyです

    DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME' : 'blog',
        'USER' : 'root',
        'PASSWORD' : 'hellyeah',
        'HOST' : '',
        'PORT' : ''
    }
}

誰かが間違っていることを教えてくれたら素晴らしいだろう..

This is because you are using Python 3 with django. There is no driver currently available for it. Since you're starting with django and Python, why not use Sqlite, it has a good Python3 driver, and will suffice for your learning experience.

You may also try using Postgres, but that has a lot more setting up to do than Sqlite.
