我在尝试应用第一次南迁移时遇到错误。我尝试了各种建议（例如删除迁移文件夹中的 .pyc 文件，转换应用程序以及尝试重新启动它，其他小提琴）。有人可以在这里建议我可以做什么吗？谢谢

在我的情况下，AttributeError: 'module' object has no attribute 'Migration'错误只是在我的迁移文件夹中有一个额外的 .py 文件。

我的迁移目录中有一个额外的实用程序模块，导致 South 窒息。将模块移动到不同的目录（在我的应用程序迁移目录之上）为我解决了这个问题。

也许有点晚了，但仍然......__init__.py您的迁移包中是否可能有任何其他包（带有 的文件夹）并且它会干扰结构？

哇。我收到AttributeError: 'module' object has no attribute 'Migration'错误，原因与上述答案完全不同。

我有一个缩进错误的迁移文件：

class Migration(SchemaMigration):
    def forwards(self, orm):
        # 

    def backwards(self, orm):
        # 
        models = {...}

相对于...

class Migration(SchemaMigration):
    def forwards(self, orm):
        # 

    def backwards(self, orm):
        # 

    models = {...}

我不知道为什么会这样，但是当我修复错误时，错误就消失了。
