Question

我正在尝试在Django 1.3中配置Postgresql 9.1。
注意：我在Ubuntu 11.10（oneric）中这样做。我也安装了postgis 1.5以与Postgresql 9.1一起使用

据我所知，我已经安装了所有必需的依赖项我也阅读了this博客的说明。

执行以下操作：

python manage.py syncdb

我收到了这个错误堆栈。

Traceback (most recent call last):
  File "manage.py", line 23, in <module>
    execute_manager(settings)
  File "/usr/local/lib/python2.7/dist-packages/django/core/management/__init__.py", line 438, in execute_manager
    utility.execute()

    raise ImproperlyConfigured('ImportError %s: %s' % (app, e.args[0]))
django.core.exceptions.ImproperlyConfigured: ImportError {ProjectName}.{ModuleName}: No module named postgresql.operations

在local_settings.py中，我将引擎名称设置为'django.db.backends.postgresql_psycopg2'。

但是在引用this之后，我将引擎名称设置为'django.contrib.gis.db.backends.postgis'，我得到以下错误堆栈：

Try using django.db.backends.XXX, where XXX is one of:
    'dummy', 'mysql', 'oracle', 'postgresql_psycopg2', 'sqlite3'
Error was: No module named postgresql.operations

我甚至保证，我安装了postgis（Postgresql-9.1-postgis）。

我哪里错了？我错过了什么？这些是我早期使用Python，Django和Postgresql以及Postgis的日子。
请在网上指出任何相关的有用链接。我尝试使用谷歌搜索，但直到现在都没有成功。

谢谢和问候

Answer 1

我遇到了同样的问题。错误的常见来源似乎是没有正确配置psycopg2。

我发现这些帖子很有用：

Answer 2

你应该使用“django.contrib.gis.db.backends.postgis”作为后端，这是肯定的;根据{{3}}。

我认为你可以在那里提交文档错误，因为文档没有提到ubuntu 11.10。
