Django遷移錯誤 - NodeNotFoundError

Question

Django verstion 1.8

嘗試遷移項目中新添加的應用程序。以下是回溯錯誤：

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') 

我在研究這方面沒有找到太多有用的信息。語法在所有模型中都是正確的。這是沒有道理的：這只是一個工作項目的副本。所以它可以在一臺電腦上運行，但不在這裏。它引用的機器模型已經創建並正在工作。有任何想法嗎？？？

Answer 1

您正在收到錯誤，因爲您嘗試運行的遷移weather.0001_initial取決於不存在的遷移machines.0006_auto_20150921_1327。

如果找不到缺失的遷移文件，則必須刪除並重新創建weather應用程序的遷移，以便它們不依賴於缺少的遷移。
