我正在尝试使用 django-pyodbc 版本连接到外部 SQL Server Express 数据库:this github link但是当我运行manage.py shell
以检查是否可以执行 ORM 命令时,我不断收到此错误
Traceback (most recent call last):

super(DatabaseOperations, self).__init__()
TypeError: __init__() takes exactly 2 arguments (1 given)
我的 settings.py 有这个:
DATABASES = {
'default': {
'ENGINE': 'sql_server.pyodbc',
'NAME': 'DBName',
'HOST': '192.168.29.1',
'USER': 'user',
'PASSWORD': 'pswd',
'PORT': 1433,
}
}
DATABASE_OPTIONS = {
'driver': '/usr/local/lib/libtdsodbc.so',
'dsn': 'FreeTDS',
'extra_params': "TDS_VERSION=8.0"
}
我完全不知道我应该做什么,所以欢迎所有想法。基本上我想要的是能够使用我制作的一个小应用程序与 SQL Server 数据库交互,同时能够使用普通的 DJango ORM 命令代替 pyodbc 连接字符串(顺便说一句,使用 pyodbc,我可以连接到SQL Server 数据库没有问题)
