我dooing一个项目中，当我尝试在Django迁移迁移不存在的父节点的错误，错误来依赖引用时，在Django

django.db.migrations.graph.NodeNotFoundError: Migration reviews.0001_initial dependencies reference nonexistent parent node (u'catalogue', u'0001_initial')

我理解的问题，但无法解决它。

我删除了所有.pyc文件和迁移文件夹。

我也删除了数据库，但这个问题仍然存在。我如何摆脱这个错误。在此先感谢。

从应用程序中删除migrations文件夹，也删除数据库并再次创建数据库。然后尝试：

1）蟒蛇manage.py makemigrations
2）Python的manage.py迁移

注意任何人阅读本：不，从来没有从任何应用程序 “删除文件夹迁移” 。这将使用已经应用了先前的迁移的您的应用程序对任何项目的任何实例进行拧紧... –
