我正在尝试使用 geoDjango 制作一个应用程序，但实际上我在运行它时遇到了一些问题。当我执行“python manage.py syncdb”命令时，出现以下错误：

File "/media/datos/Proyectos/CualBondi/git/cualbondi/myapp/models.py", line 10, in <module>
from django.contrib.gis.db import models
File "/usr/local/lib/python2.6/dist-packages/django/contrib/gis/db/models/__init__.py", line 5, in <module>

from django.contrib.gis.db.backend import SpatialBackend, gqn
ImportError: cannot import name SpatialBackend

我在这里给你一些额外的信息：

Django 1.3.1
Python 2.6
Ubuntu 10.04
PostgreSQL 8.4.8

你有什么想法吗？非常感谢！

也许这有帮助，SpatialBackend 似乎已被弃用。阅读下面的警告。

$ python manage.py shell

>>> from django.contrib.gis.db.backend import SpatialBackend, gqn

All functionality of `SpatialBackend` has been moved to the `ops` attribute of the spatial database backend.  A `SpatialBackend` alias is provided here for backwards-compatibility, but will be removed in 1.3.

我在 django 1.3.0 上，似乎工作得很好，但只有那个警告。
