GeoDjango GDALException - OGR失败

Question

安装GeoDjango后，我想在管理面板中创建一个“位置”对象，该对象使用地图上的地址和点。提交表单后，我收到错误，如此...

GDALException at /admin/maps/location/add/
OGR failure.

我试过看类似的问题，like here，但没有一个解决方案有效。此外，搜索“无法加载PROJ.4库”（第一个追溯线）没有取得任何成功。

任何帮助，将不胜感激！ - 如果我应该使用settings.py或其他相关文件更新此问题，请与我们联系。

完全追溯：

编辑：为Location添加了我的models.py和admin.py

models.朋友:

from __future__ import unicode_literals
from django.contrib.gis.db import models
from django.contrib.gis.geos import Point
from django.core.exceptions import ObjectDoesNotExist
from django.conf import settings
from . import utils

COUNTRIES=((0,'UK'),(1,'USA'),(2,'CA'),(3,'AUS'),(4,'JP'),(5,'FR'))
class Location(models.Model):
    name=models.CharField(max_length=120,verbose_name='House name/number',blank=True)
    first_addr=models.CharField(max_length=45,verbose_name='Address line 1',blank=False)
    second_addr=models.CharField(max_length=45,verbose_name='Address line 2',blank=True)
    town=models.CharField(max_length=45,verbose_name='Town/City',blank=False)
    state=models.CharField(max_length=45,verbose_name='State/Province',blank=False)
    zip_code=models.CharField(max_length=12,verbose_name='Postal/Zip Code',blank=False)
    country=models.IntegerField(verbose_name='Country',blank=False,null=False,choices=COUNTRIES)
    point=models.PointField(default='POINT (0 0)',srid=4326)
    dt_created=models.DateTimeField(auto_now_add=True)
    dt_updated=models.DateTimeField(auto_now=True)
    class Meta:
        verbose_name = 'Location'
    def __unicode__(self):
        return self.name
    def __str__(self):
        return self.name
    @property
    def longitude(self):
        return self.point[0]
    @property
    def latitude(self):
        return self.point[1]

admin.朋友:

from __future__ import unicode_literals
from django.contrib.gis import admin
from django.contrib.gis.geos import GEOSGeometry
from django.contrib.auth.admin import UserAdmin
from maps.models import *

class LocationAdmin(admin.OSMGeoAdmin):
    model = Location
    list_display = ['name','first_addr','second_addr','town','state','zip_code','country','longitude','latitude','dt_created','dt_updated']
    search_fields = ['first_addr','second_addr','town','state','zip_code']

admin.site.register(Location,LocationAdmin)

如果在setting.py文件的顶部添加以下命令，则会修复此错误

    if os.name == 'nt':
    import platform
    OSGEO4W = r"C:\OSGeo4W"
    if '64' in platform.architecture()[0]:
        OSGEO4W += "64"
    assert os.path.isdir(OSGEO4W), "Directory does not exist: " + OSGEO4W
    os.environ['OSGEO4W_ROOT'] = OSGEO4W
    os.environ['GDAL_DATA'] = OSGEO4W + r"\share\gdal"
    os.environ['PROJ_LIB'] = OSGEO4W + r"\share\proj"
    os.environ['PATH'] = OSGEO4W + r"\bin;" + os.environ['PATH']
