django.db.migrations.exceptions.NodeNotFoundError: Migration apitest.0001_initial dependencies reference nonexistent parent node ('product', '0001_initial')

问题原因:由于'product' 应用下的'0001_initial'文件不存在,而在 apitest应用下的0001_initial 文件中引用了product中的迁移记录

问题解决:删除 apitest->migrations下的0001_initial .py文件,再重新执行命令
