Python manage.py runserver raise NotSupportedError( django.db.utils.NotSupportedError: PostgreSQL 11 or lated (发现 10.22)

Question

我是 python 和 django 的初学者，我正在使用 Windows 10-32 位计算机。我不明白问题出在哪里，我改变了什么但是当我运行 manage.py 时，它得到了这个：

$ python manage.py runserver

    raise NotSupportedError(
django.db.utils.NotSupportedError: PostgreSQL 11 or later is required (found 10.22).

然后，我知道我的 postgresql 没有更新，但我在 32 字节的窗口上，我不能使用 postgres 11 或更高版本。我试图撤销我的上次迁移，但它不起作用。

感谢您的帮助 ！

我猜你正在使用 django 4.*。 尝试使用 django 3.2 版本。
