我使用pip3安装在ubuntu 16.04 django 1.11上，然后安装了oracle mysql-connector-python。为什么会出现此错误？我该如何解决？根据教程，即使没有定义模型，迁移也会运行。
使用pip3安装
pip3 install --egg http://dev.mysql.com/get/Downloads/Connector-Python/mysql-connector-python-2.1.6.zip
我的数据库配置
DATABASES = {
'default': {
'NAME': 'user_data',
'ENGINE': 'mysql.connector.django',
'USER': 'mysql_user',
'PASSWORD': 'priv4te',
'OPTIONS': {
'autocommit': True,
},
}
}
我跑的命令 python3 /home/django/workspace/mysite/manage.py migrate
错误
