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，它使用地图上的地址和点。 提交表单后，我收到这样的错误...

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

我曾尝试查看类似的问题， 例如 here ，但没有一个解决方案有效。 此外，搜索“无法加载 PROJ.4 库”（第一个回溯行）也没有成功。

任何帮助将不胜感激！ - 让我知道我是否应该用我的 settings.py 或其他相关文件更新这个问题。

完整追溯：

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

编辑：为位置添加了我的 models.py 和 admin.py

模型.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]

管理.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)

Answer 1

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']

将这些行添加到 setting.py 中对我有用。 但是，当您添加 GDAL_LIBRARY_PATH 时，请检查您拥有的 gdal 库是什么，并添加 gdal 库之一，例如“gdal204”

Answer 2

如果您在 setting.py 文件的顶部添加以下命令，将修复此错误

    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']

Answer 3

如果您使用的是 Windows 操作系统和一些设置文件，请使用以下行：

GDAL_LIBRARY_PATH = r'C:\\OSGeo4W64\\bin\\gdal300'

我将它用于我的基于 Django 的应用程序。
