MySQL無法與Python 3.6和Django 1.9一起使用

Question

我正在嘗試使用django 1.9連接mysql db，而python版本是3.6。 使用數據庫連接字符串時，出現以下錯誤。 如果我注釋掉數據庫連接字符串，則說明該站點加載良好。 誰能告訴我這是什么問題。

我們用來嘗試連接到Mysql的數據庫設置

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
    'HOST': 'AAAAAAAAAAAAAAAAA',
        'NAME': 'ZZZZZZZZZZZZZZZZ',
    'USER': 'YYYYYYYYYYYYYYYY',
        'PASSWORD': 'XXXXXXXXXXXX',
    'PORT': '3306',
        'OPTIONS': {
            'init_command': 'SET storage_engine=INNODB',
        },
    }
}

Answer 1

通常，此錯誤表示Django項目中某處存在錯誤。 可能很難找到。

您可以嘗試多種解決方案，例如：1.重新啟動Apache 2.執行makemigrations並遷移Django命令3.修改wsgi.py文件，以便您可以管理異常

在File "/home/abhadran/myenv/lib/python3.6/site-packages/django/apps/registry.py"行中的一點說明表明您使用的是Python 3.6，而不是您在Python 3.5中提到的您的描述。

直到Django 1.11為止，Python 3.6才正式受支持，因此您可能必須升級Django版本或在venv中降級Python。
