Python 我能'；由于AttributeError，无法使用south同步数据库

在尝试迁移时出错之后，现在我面临着

south

包的另一个问题

运行

manage.py syncdb

或

manage.py schemamigration MyApp--initial

我得到：

提到该问题已通过新版本（

0.8.4

）解决，但不适用于我，因为我有最新版本

我正在运行python3.3虚拟环境-有线索吗

问题是我在整个项目中使用了python3.3，但是最初的

python manage.py syncdb

命令是使用pyhon2.7输入的，这将在以后给我带来一些问题

我在从头开始生成项目后注意到了这一点，并在中看到了一个错误

---

然后我删除了postgre sql中的所有信息，在

source bin/activate

之后，运行

python3 manage.py syncdb

只是为了完整起见，我在评论中突出显示@rara_tiru的答案作为答案，因为这也是我的问题：当迁移文件夹被删除时，我的应用程序中还有一个迁移文件夹，成功了。使用Python3.3/South 1.0/Django 1.6.5.

至少在Django 1.5中，如果您有空的“迁移”目录，

AttributeError:“module”对象没有属性“\uu file\uuuuuuuu”

也会发生错误。

我想看看这个问题的解决方案，因为我也有这个…@RobDel我找到了解决方案。请参见下面的答案。@RobDel在我的例子中，问题是当我发出命令

/manage.py schemamigration app--initial

时，

迁移

目录存在。删除它之后，一切都很好。我还删除了数据库迁移条目，一切正常。谢谢
