GeoDjango GDALException - OGR failure

问题

After installing GeoDjango, I wanted to create a 'Location' object in the admin panel which uses an address and a point on a map. After submitting the form, I get an error like so...

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

I have tried looking at similar questions, like here, but none of the solutions have worked. Additionally, searching for 'unable to load PROJ.4 library' (first traceback line) didn't come with any success.

Any help would be appreciated! - Let me know if I should update this question with my settings.py or other relevant files.

Full traceback:

GDAL_ERROR 6: Unable to load PROJ.4 library (libproj.dylib), creation of OGRCoordinateTransformation failed.

Edit: Added my models.py and admin.py for Location

models.py:

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.py:

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)

import os
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'] = "C:\Program Files\GDAL\gdal-data" 
    os.environ['PROJ_LIB'] = OSGEO4W + r"\share\proj"
    GDAL_LIBRARY_PATH = r'C:\OSGeo4W64\bin\gdal204'
    os.environ['PATH'] = OSGEO4W + r"\bin;" + os.environ['PATH']

Adding these lines into the setting.py works for me. But when you adding the GDAL_LIBRARY_PATH check what are the gdal libraries you have and add one of the gdal library like 'gdal204'

回答2:

This error will fixed if you add following command at the top of your setting.py file

    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']
