python - 在 Django 中为 ubuntu 11.10 设置 Postgresql 9.1 数据库

Question

我正在尝试在 Django 1.3 中配置 Postgresql 9.1 。
注意:我在 Ubuntu 11.10 (oneric) 中执行此操作。我还安装了 postgis 1.5 以与 Postgresql 9.1 一起使用

据我所知，我已经安装了所需的所有依赖项。
我阅读了 this 的说明还有博客。

执行以下操作:

python manage.py syncdb

我收到此错误堆栈。

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()
  File "/usr/local/lib/python2.7/dist-packages/django/core/management/__init__.py", line 379, in execute

    klass = load_command_class(app_name, subcommand)

    module = import_module('%s.management.commands.%s' % (app_name, name))

    __import__(name)

    import django.template.loaders.app_directories

    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:

    Traceback (most recent call last):

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

我什至确保，我已经安装了 postgis (Postgresql-9.1-postgis)。

我哪里出错了？我缺少什么？这是我早期使用 Python、Django、Postgresql 和 Postgis 的经历。
请指出网络上任何相关的有用链接。我尝试过谷歌搜索，但到目前为止还没有成功。

感谢和问候

我也遇到了同样的问题。错误的常见来源似乎是 psycopg2 未正确配置。

我发现这些帖子很有帮助:
