导入错误：无法导入名称'；python_2_unicode_兼容'；为Django邀请运行迁移时

首先，我想提一下我是Django的初学者。我正在尝试在我的应用程序上安装Django邀请，以发送注册邀请。我跟着他们

我还安装了pip的以下所有要求：

覆盖率==4.5.4 薄片8==3.7.9 冷冻枪==0.3.12 模拟==3.0.5 pytest==5.2.2 pytest django==3.6.0 pytest cov==2.8.1 tox==3.14.0

但在第一次运行迁移时，我总是遇到同样的错误：

    main()
  File "manage.py", line 17, in main

知道问题是什么吗

谢谢

如果您愿意，它应该会起作用

然后，您需要做的就是在您的models.py.

中将

django.utils.encoding

替换为

six

——这是django 3的一个已知兼容性问题。好的，谢谢，我将尝试以自己的方式解决这个问题。
