python - __classcell__传播了RuntimeError : __class__ not set defining 'AbstractBaseUser' as .

Question

在为项目手动设置 PostgreSQL数据库后，尝试迁移数据库时遇到此错误。

当出现此错误时，我试图运行从github fork 的克隆的quora项目。

请遵循完整的错误描述:

RuntimeError: __class__ not set defining 'AbstractBaseUser' as <class 'django.contrib.auth.base_user.Abstract BaseUser'>. Was __classcell__ propagated to type.__new__?

跟踪:

检查您的python和django版本。我有同样的问题，必须通过pyenv安装以前的python。
