GeoDjango:PostgreSQL没有运行迁移,对象没有属性'geo_db_type

Question

Django v1.11.5

我正在尝试安装GeoDjango来玩GoogleMaps.

我为MAC安装了PostgreSQL应用程序并安装了pip install psycopg2.我还用home-brew来安装GDAL.

编辑settings.py添加:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'djangodb',
        'USER': 'admin',
        'PASSWORD': '',
        'HOST': 'localhost',
        'PORT': '5432',
    }
}

但是,当我运行python manage.py迁移时,我得到:AttributeError: 'DatabaseOperations' object has no attribute 'geo_db_type'

我创建了用户:CREATE DATABASE djangodb OWNER admin;

完全错误:

正在运行迁移:应用users.0011_location ...

我试过类似的问题: 在执行syncdb时,获取'DatabaseOperations'对象没有属性'geo_db_type'错误

您需要更改DATABASES设置才能使用postgis后端,

'ENGINE': 'django.contrib.gis.db.backends.postgis',

并添加'django.contrib.gis'到INSTALLED_APPS.
