django-pyodbc-azure 2.1.0.0 不支持 Django 2.1.0

Question

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

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

我们尝试了很多 Django 版本，例如 2.x、2.0.4、2.1，所有版本似乎都抛出相同的错误，即

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
        },
    }
}

如有任何线索，我们将不胜感激。谢谢

Answer 1

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

Answer 2

通过从 https://pypi.org/project/django-pyodbc-azure/#files 下载 django-pyodbc-azure 2.1.0.0 的 wheel file 并使用命令 pip install django_pyodbc_azure-2.1.0.0-py3-none-any.whl.

安装解决了这个问题
