django-haystack空间搜索需求？

Question

我正尝试使用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，我不确定为什么。 在干草堆中进行空间搜索是否需要完整运行的django.contrib.gis（geodjango）？ 换句话说：我是否必须为geodjango安装所有c库，配置postgis，然后才能在干草堆中使用Point类？

软件版本：

• Django 1.6
• django-干草堆2.1.0
• pyelasticsearch 0.6.1
• 弹性搜索0.90.7

我通过安装libgeos和libgeos-dev解​​决了问题

sudo apt-get install libgeos-dev
