django-haystack空間搜索需求？

Question

我正嘗試使用django-haystack進行地理空間查詢，如下所述： http : //django-haystack.readthedocs.org/en/latest/spatial.html我正在使用Elasticsearch作為后端。 我根據文檔創建了search_indexes，配置了django，當我第一次嘗試使用rebuild_index管理命令時，我看到了一個錯誤：

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

干草堆用於從django.contrib.gis.geos進行空間搜索的點無法導入，我不確定為什么。 在干草堆中進行空間搜索是否需要完整運行的django.contrib.gis（geodjango）？ 換句話說：我是否必須為geodjango安裝所有c庫，配置postgis，然后才能在干草堆中使用Point類？

軟件版本：

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

我通過安裝libgeos和libgeos-dev解​​決了問題

sudo apt-get install libgeos-dev
