Django Taggit - AttributeError:无法设置属性

昨天我安装PostgreSQL作为我正在开发的网站的数据库.安装后,计算机重新启动.

怎么了？我丢失了所有环境变量(我正在使用Windows 10).所以我不得不重新添加python到路径.

之后,我创建了db,我替换了settings.py上的数据.我运行网站,但它给出了一个错误.所以我安装了psycopg2让postgres使用django.没门.

我决定暂时回到sqlite3,所以我编辑了settings.py并运行了网站.错误告诉我没有名为Taggit的应用程序.(???)这不正常.我安装了它,一切正常.我重新安装了它(版本0.17.1).

我不知道如果这些事件是连通的...这就是我告诉你一切的原因.现在:在我使用django Taggit的每一个项目中,我都会收到同样的错误(即使是我几个月没打开的那个)...

我试图重新安装django-taggit但没有改变.

你能帮我理解为什么吗？

我有同样的问题,安装了最新版本的django-taggit并且它有效.
