python - geodjango 中的 "cannot import name Polygon"

Question

我正在尝试关注 this simple tutorial在我的网页上的传单 meap 上显示标记。但是，我收到以下错误:

from django.contrib.gis.geos.geometry import Polygon ImportError: cannot import name Polygon

由于这条语句 from djgeojson.views import GeoJSONLayerView 在我的 urls.py

我不确定如何解决这个问题，我已经为 geodjango 安装了所有必需的依赖项，但找不到名为“Polygon”的包..

这是完整的错误:

Django 1.9 的导入似乎中断了 https://github.com/makinacorpus/django-geojson/issues/68
