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.

from django.contrib.gis.geos import Point
ImportError: cannot import name Point
haystack 用于从 django.contrib.gis.geos 进行空间搜索的点无法导入，我不确定为什么。一个完整的工作 django.contrib.gis (geodjango) 是 haystack 中空间搜索的要求吗？换句话说:我必须为 geodjango 安装所有 c 库，配置 postgis，然后才能在 haystack 中使用 Point 类吗？
软件版本:
- Django 1.6
- django-haystack 2.1.0
- pyelasticsearch 0.6.1
- Elasticsearch 0.90.7
请您参考如下方法:
我通过安装 libgeos 和 libgeos-dev 解决了这个问题
sudo apt-get install libgeos-dev
