不支持Django 3.0.1是什么意思？

What is mean Django 3.0.1 is not supported?

推荐答案

您使用的sql_server软件包与Django 3.0或更高版本不兼容。从您的问题尚不清楚，您使用的是哪个sql_server软件包（是否为django-pyodbc？），但是大多数软件包尚未添加对Django 3.0的支持。

The sql_server package you're using isn't compatible with Django 3.0 or higher. It's not clear from your question which sql_server package you're using (is it django-pyodbc?) but most of the packages haven't added support for Django 3.0 yet.

使用与您兼容的Django版本django-pyodbc软件包（请查阅软件包的文档，可能您应该使用Django 2.1或2.2）或将打包并对其进行修改以支持Django 3.0。

Use a version of Django that is compatible with you django-pyodbc package (consult the documentation of the package, probably you should be using Django 2.1 or 2.2) or fork the package and modify it to support Django 3.0.
