Question

我正在尝试使用django-haystack进行地理空间查询，如下所述：http://django-haystack.readthedocs.org/en/latest/spatial.html我正在使用elasticsearch作为后端。我根据文档创建了search_indexes，配置了django，当我第一次尝试使用rebuild_index管理命令时，我看到了一个错误：

python manage.py rebuild_index --settings=myproject.settings.local

WARNING: This will irreparably remove EVERYTHING from your search index in connection 'default'.
Your choices after this are to restore from backups or rebuild via the `rebuild_index` command.
Are you sure you wish to continue? [y/N] y
Removing all documents from your index because you said so.
All documents removed.

ImportError: cannot import name Point

干草堆用于从django.contrib.gis.geos进行空间搜索的点无法导入，我不知道为什么。一个完整的工作django.contrib.gis（geodjango）是大海捞针空间搜索的要求吗？换句话说：我必须为geodjango安装所有c库，配置postgis，之后我才能在haystack中使用Point类吗？

sotfware的版本：

Django 1.6
django-haystack 2.1.0
pyelasticsearch 0.6.1
elasticsearch 0.90.7

我通过安装libgeos和libgeos-dev

解决了这个问题

sudo apt-get install libgeos-dev

django-haystack空间搜索要求？
