使用django-mssql连接到MS SQL Server时出现问题

Question

我正在尝试使用django-mssql连接到带有Django 1.4.2的MS SQL Server2008 R2，以下是我的数据库设置：

DATABASE_ENGINE   = 'sqlserver_ado'
DATABASE_NAME     = 'dbtest'
DATABASE_USER     = 'App'
DATABASE_PASSWORD = '*********'
DATABASE_HOST     = 'localhost'
DATABASE_OPTIONS  =  {
            'provider': 'SQLNCLI10',
            'extra_params': 'DataTypeCompatibility=80;MARS Connection=True;',
        } 

DATABASES = {
  'default': {
    'ENGINE':   DATABASE_ENGINE,
    'NAME':     DATABASE_NAME,
    'USER':     DATABASE_USER,
    'PASSWORD': DATABASE_PASSWORD,
    'HOST':     DATABASE_HOST,
    'OPTIONS' : DATABASE_OPTIONS,
  },
}

这是我尝试同步数据库时得到的错误

    Traceback (most recent call last):
  File "C:\Python27\DataSatellite\manage.py", line 11, in <module>

Finished "C:\Python27\DataSatellite\manage.py syncdb" execution.

我已经到处找过了，我似乎无法理解和解决这个问题。我希望有人能帮助我！谢谢!

编辑：

我已经创建了数据库。我还使用django-pyodbc连接到数据库，并成功地从数据库读取和写入。但是当我使用Apache时，django-pyodbc会带来问题，这就是为什么我决定尝试使用django-mssql。然而，我不理解它带来的错误。

我的Django (1.4.2)和Python (2.7)安装在Windows上，而我使用的是Apache and服务器。

更新pywin32以构建217或更高版本。我在stackoverflow上发现了另一个同样的问题(在另一个主题上)：

Python COM server throws 'module' object has no attribute 'VARIANT'
