【问题标题】：Issue with Geodjango OGR failure - GDAL ExceptionGeodjango OGR 失败的问题 - GDAL 异常
【发布时间】：2019-08-28 18:42:10
【问题描述】：

我已经在 django 中构建了模型，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 }}”中突出显示作为错误原因。这是屏幕截图Admin view for adding data to the model

i get this right away after clicking save

有人经历过吗？有什么帮助吗？

谢谢

更新：我收到此错误：

【问题讨论】：

您能否分享有关您问题中的错误的更多信息？请添加以下内容： - 您尝试填写的模型 - 您使用的管理表单 - 错误跟踪（不是截图）尝试遵循该指南：stackoverflow.com/help/how-to-ask
感谢约翰的回复，我已经更新了问题
你在windows上吗？如果是，这个答案对您有帮助吗：stackoverflow.com/questions/49139044/…?
嗨，约翰，是的，我在 Windows 上，我已经看到了这个答案，我做了这些步骤，（OSGEO 64）等等......但没有用
好的，所以我找到了解决方案，谢谢

【解决方案1】：

抱歉复制/粘贴，只是稍微修改了@Kiwi 的答案。我尝试在原始答案中添加注释，但无法添加格式化代码。

现在您似乎无法再安装 64 位版本的 OSGEO4W。我安装了唯一可用的版本here 并修改了@Kiwi 的答案以反映缺少 64 位。我在 Windows 10 上。下面的一切正常。

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']

【讨论】：

【解决方案2】：

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" #OSGEO4W + r"\share\gdal"
    os.environ['PROJ_LIB'] = OSGEO4W + r"\share\proj"
    os.environ['PATH'] = OSGEO4W + r"\bin;" + os.environ['PATH']

问题是这段代码通过 geodjango 强制执行其中定义的路径，所以即使你设置了系统变量，这段代码仍然会支配系统变量。

如果有人对 OGR 有任何疑问，请随时发表评论

我添加了它，但仍然有同样的问题，当我尝试使用 geom 查看数据库中的实例时出现错误
你使用的是windows 32位版本吗？
我遇到了同样的问题。
