Question

我们正尝试将Django-2.1与MS SQL Server 2012连接起来。我们正在寻找用于此目的的模块，并偶然发现django-pyodbc-azure。我们安装了pip，并在重新启动应用程序时收到以下错误消息：

)
django.core.exceptions.ImproperlyConfigured: Django 2.1.0 is not supported.

我们尝试了许多版本的Django，例如2.x，2.0.4、2.1，所有版本似乎都抛出了相同的错误，

Django 2.x.x is not supported.

settings.py中的数据库信息：

DATABASES = {
    'default': {
        'ENGINE': 'sql_server.pyodbc',
        'HOST': 'xxxxxx,1433',
        'USER': 'xxxxxxxx',
        'PASSWORD': 'xxxxxxxx',
        'NAME': 'xxxxxx',
        'OPTIONS': {
            'driver': 'ODBC Driver 17 for SQL Server',
            'host_is_server': True
        },
    }
}

任何线索都将不胜感激。谢谢。

Answer 1

通过从https://pypi.org/project/django-pyodbc-azure/#files下载wheel file的{{1}}并使用命令django-pyodbc-azure 2.1.0.0进行安装，解决了此问题。

Answer 2

几个月前，我遇到了同样的问题。最终的组合版本为python 3.5和django 1.11，最新版本为django-pyodbc-azure

django-pyodbc-azure 2.1.0.0不支持Django 2.1.0
