运行Python服务器所需的帮助

Question

我正在尝试执行'python manage.py runserver‘，并且一直收到这个错误消息。我曾尝试使用SQL_Server.pyodbc和SQLServer_ADO作为SQL引擎-但这似乎不能解决我收到的错误。我还从我的项目中排除了一些新的python文件，这些文件是我最近添加的，因为在添加新的python文件之前，系统工作得很好。

编辑:我已经将Django升级到了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。要获得更具体的帮助，我想你必须添加更详细的信息。
