python - Mysql 不适用于 python 3.6 和 django 1.9

Question

我正在尝试将 mysql db 与 django 1.9 连接，python 版本是 3.6。使用数据库连接字符串我收到以下错误。如果我注释掉数据库连接字符串，则该网站加载正常。谁能告诉我这有什么问题吗？

我的点卡住了

Django==1.9.12
django-tastypie==0.13.3
mod-wsgi==4.5.15
mysql-connector-python==2.0.4
mysqlclient==1.3.10
PyMySQL==0.6
python-dateutil==2.6.0
python-mimeparse==1.6.0
requests==2.13.0
six==1.10.0

我们用来尝试连接到 Mysql 的数据库设置

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，这个错误意味着Django项目中的某个地方有错误。可能很难找到。

您可以尝试多种解决方案，例如: 1. 重新启动 Apache 2.执行makemigrations并迁移Django命令 3.修改您的wsgi.py文件以便您可以管理异常

请注意，在 File "/home/abhadran/myenv/lib/python3.6/site-packages/django/apps/registry.py" 行中表明您正在使用正如您在描述中提到的那样，Python 3.6 而不是 Python 3.5。

Python 3.6 在 Django 1.11 之前得到正式支持，因此您可能必须升级 Django 版本或在 venv 中降级 Python。
