【问题描述】：
我正在尝试执行“python manage.py runserver”并不断收到此错误消息。我曾尝试使用 SQL_Server.pyodbc 和 SQLServer_ADO 作为 SQL 引擎 - 但这似乎无法解决我收到的错误。我还从我最近添加的项目中排除了一些新的 python 文件，因为在添加新的 python 文件之前系统运行良好。

编辑：我已将 Django 升级到 3.0.2，我还安装了 django-mssql-backend。但是，现在我在命令提示符中收到以下错误：

看起来数据库不兼容或配置不正确。如需更具体的帮助，您必须添加更详细的信息。
-
请您概述所需的更详细信息吗？我可以使用 SQL Server Management Studio 连接并登录到 SQL Server。
-
您能分享您的
DATABASES设置和您的Question模型吗？ -
DATABASES = { 'default': { 'ENGINE': "sqlserver_ado", 'HOST': "websiteurlhere,1434", 'USER': "username", 'PASSWORD': "password", 'NAME': "Django", 'OPTIONS': { 'driver': 'ODBC Driver 17 for SQL Server', 'unicode_results': True, 'host_is_server': True }, } }
