django错误django.db.migrations.exceptions.NodeNotFoundError：迁移app.0001_initial的依赖引用不存在的父节点（’auth’，’0011_update_proxy_permissions’）
如果在Django中遇到以下错误，可能是因为引用了不存在的父节点（本例中是auth）。
django.db.migrations.exceptions.NodeNotFoundError: Migration app.0001_initial dependencies reference nonexistent parent node ('auth', '0011_update_proxy_permissions')
在这种情况下，升级Django版本至2.2以上可能会修复问题。对于本次情况而言，可以考虑升级至2.2.4版本。
将django版本升级至2.2.4。
pip3 install django==2.2.4 --user
在manage.py所在的位置运行runserver。
python manage.py runserver
一切顺利地运行了runserver和migrate。
C:\Users\hoge\Desktop\hoge\hoge>python manage.py runserver
