Django 迁移错误 - NodeNotFoundError

Django 版本 1.8

尝试迁移我的项目中新添加的应用程序。这是回溯错误：

Traceback (most recent call last):

我在研究这个问题时没有找到太多有用的信息。所有模型中的语法都是正确的。这是没有意义的：这只是一个工作项目的副本。所以它可以在一台计算机上运行，​​但不能在这里运行。它引用的机器模型已经创建并且正在运行。有任何想法吗？？？

您收到错误是因为您尝试运行的迁移，weather.0001_initial，取决于迁移machines.0006_auto_20150921_1327这是不存在的。

如果找不到丢失的迁移文件，则必须删除并重新创建迁移weather应用程序，这样它们就不会依赖于丢失的迁移。
