1、看下报错的url 所在位置，将urlpatterns=[]改为urlpatterns=()例如：

2、检查数据库是否连接正确，删处数据库中的表，每个模块中的migrations文件夹的文件都删除只留下__init__.py(注意：每个模块的migrations文件夹都只留下__init__.py其余删除)

3、重新迁移数据库
python manage.py makemigrations
python manage.py migrate
4、重新启动项目

python manage.py runserver

如果我的回答解决了你的疑惑，请采纳，祝学习愉快~

同学你好：在settings.py中加入 AUTH_USER_MODEL ="app.models"其中user为app名，models为模型名。同学加入之后再试一下祝同学学习愉快！
