我试图让我的django项目在windows10计算机上运行,它在尝试建立数据库连接时抛出了一个非常不具体的错误。在这个so post中,问题在于身份验证,但在这个post中,显示的是有关错误的详细信息,而不是<\null>,这提供了很少的信息。
整个错误如下所示:

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

使用python3.6.6和mysqlclient 1.3.13,尽管也尝试过1.3.12。
数据库设置:
DATABASES = {
'default': {
'ENGINE': "django.db.backends.mysql", # 'mysql.connector.django'
'NAME': 'testdb',
'USER': 'root',
'PASSWORD': 'password',
'HOST': 'localhost',
'PORT': '3306',
'OPTIONS': {
'autocommit': True,
},
},
}
