我正在建立一个网站，并试图创建一个自定义的用户到用户消息传递系统，所以我安装了，也许还有其他一些事情，突然，当我尝试运行服务器时，出现以下错误：
I'm building a website and I was trying to create a custom user-to-user messaging system so I installed django-messages and maybe a few other things, and suddenly when I tried to run my server I get the following error :

在我看来这是中文，我不明白此错误的任何一行，有人可以帮助我吗？
我进行了一些研究，它似乎与程序包名称 6 有关，但是我找不到解决方案。我可以为您提供我的代码，但我不知道您需要哪个文件，因此随时在评论中索取一个文件，然后我将相应地编辑我的帖子。
It sounds like chinese to me, I don't understand a single line of this error, can someone help me ?I've made a few researchs, it looks like it's related to a package name six but I was not able to find a solution. I can provide you my code if it's needed but I don't know which file you need so feel free to ask for a file in the comments and I will edit my post accordingly.
预先感谢！
推荐答案
您正在使用Django 3，其中所有 。 django消息仍然依赖于这些消息，并且正在尝试并且无法导入它们。
You are using Django 3, where all the Python 2 compatibility APIs that used to be bundled with Django were removed. django-messages still depends on these, and is trying and failing to import them.
您要么需要降级到Django 2.2，或等待 django-messages 更新以获取Django 3支持。
You either need to downgrade to Django 2.2, or wait for django-messages to be updated for Django 3 support.
库中出现此类错误-这意味着该库与Django 3尚不兼容。
This applies for any library in which you get such errors - it means the library is not compatible yet with Django 3.
