当我运行python manage.py makemigrations时，会发生以下错误：
OSError: [WinError 126] The specified module could not be found

我的models.py如下所示：
from django.contrib.gis.db import models
class WorldBorder(models.Model):
# Regular Django fields corresponding to the attributes in the
# world borders shapefile.
name = models.CharField(max_length=50)
area = models.IntegerField()
pop2005 = models.IntegerField('Population 2005')
fips = models.CharField('FIPS Code', max_length=2)
iso2 = models.CharField('2 Digit ISO', max_length=2)
iso3 = models.CharField('3 Digit ISO', max_length=3)
un = models.IntegerField('United Nations Code')
region = models.IntegerField('Region Code')
subregion = models.IntegerField('Sub-Region Code')
lon = models.FloatField()
lat = models.FloatField()
# GeoDjango-specific: a geometry field (MultiPolygonField)
mpoly = models.MultiPolygonField()
# Returns the string representation of the model.
def __str__(self):
return self.name
另外，我认为我的Postgis安装有问题，但不知道从哪里开始。我按照https://docs.djangoproject.com/en/2.0/ref/contrib/gis/install/#windows安装geodjango的说明进行操作。但是无法使用Stack Builder安装postgis。所以我使用https://download.osgeo.org/postgis/windows/pg96/的安装程序安装了它。
我的PostgreSQL版本是9.6。我正在使用conda环境。
