Django迁移错误 - NodeNotFoundError

Question

Django verstion 1.8

尝试迁移项目中新添加的应用程序。以下是回溯错误：

Traceback (most recent call last): 
    File "./manage.py", line 10, in <module> 
    execute_from_command_line(sys.argv)

    raise exc 
django.db.migrations.graph.NodeNotFoundError: Migration weather.0001_initial dependencies reference nonexistent parent node (u'machines', u'0006_auto_20150921_1327') 

我在研究这方面没有找到太多有用的信息。语法在所有模型中都是正确的。这是没有道理的：这只是一个工作项目的副本。所以它可以在一台电脑上运行，但不在这里。它引用的机器模型已经创建并正在工作。有任何想法吗？？？

Answer 1

您正在收到错误，因为您尝试运行的迁移weather.0001_initial取决于不存在的迁移machines.0006_auto_20150921_1327。

如果找不到缺失的迁移文件，则必须删除并重新创建weather应用程序的迁移，以便它们不依赖于缺少的迁移。
