Question

尝试从django的1.7.4升级到1.8;但是，当我运行服务器时，我现在得到了

There is no South database module 'south.db.mysql' for your database. Please either choose a supported database, check for SOUTH_DATABASE_ADAPTER[S] settings, or remove South from INSTALLED_APPS.

错误消息，但不起作用。我的INSTALLED_APPS中没有'South'。并且不记得在这个项目上曾经使用过南方。我的所有模型实际上都是手动管理的。

我该如何解决这个问题？

由于

[编辑] 正如您将看到的，我有很多“升级”修复程序要做，但仍然不明白为什么它在“南方”失败而我不使用它。

There is no South database module 'south.db.mysql' for your database. Please either choose a supported database, check for SOUTH_DATABASE_ADAPTER[S] settings, or remove South from INSTALLED_APPS

Answer 1

我想把问题保留原样，并显示我在这里找到的答案：

pip uninstall South

不确定为什么让南方包引发这种错误，因为我的项目没有使用它！但它似乎解决了我的问题。

Answer 2

如果您的项目具有南迁移依然存在于“迁移”文件夹中的依赖项，而不是“south_migrations”文件夹

，则会出现此错误

Answer 3

在modules.py中更改：

class Session(models.Model):
    ...
    ip = models.IPAddressField(blank=True)

到

ip = models.GenericIPAddressField(blank=True, null=False)

升级1.7.4到django 1.8 south.db.mysql错误，不使用南
