leaflet - Geodjango OGR 失败的问题 - GDAL 异常
问题描述
我已经建立了 django 中的模型,但是一旦添加数据并单击保存我的应用程序崩溃
我得到 GDAL 异常 - OGR 失败,它在崩溃页面“{{ field.field }}”中突出显示为错误的原因。这是用于将数据添加到模型的屏幕截图管理视图
有人经历过吗?有什么帮助吗?
谢谢
更新:我收到此错误:

解决方案
为复制/粘贴而道歉,只是稍微修改了@Kiwi 的答案。我尝试在原始答案中添加评论,但无法添加格式化代码。
现在看来您无法再安装 64 位版本的 OSGEO4W。我在这里安装了唯一可用的版本并修改了@Kiwi 的答案以反映缺少 64 位。我在 Windows 10 上。下面的一切都很好。
import platform
import environ
WINDOWS = platform.system() == "Windows"
if WINDOWS:
# the below needs to change for linux
GDAL_LIBRARY_PATH = r'C:\OSGeo4W\bin\gdal303.dll'
GEOS_LIBRARY_PATH = r'C:\OSGeo4W\bin\geos_c.dll'
OSGEO4W = r"C:\OSGeo4W"
os.environ['OSGEO4W_ROOT'] = OSGEO4W
os.environ['GDAL_DATA'] = "C:\Program Files\GDAL\gdal-data" # OSGEO4W + r"\share\gdal"
os.environ['PROJ_LIB'] = OSGEO4W + r"\share\proj"
os.environ['PATH'] = OSGEO4W + r"\bin;" + os.environ['PATH']
