我以前做过十几次，但这次有些东西不工作了。
按照文档：

我正在尝试在 Windows 机器上设置 GeoDjango（这是在 paperspace.com 上设置的虚拟 Windows 10）。我的 PATH 设置似乎有问题，但我无法弄清楚它是什么。我已经运行了说明中突出显示的命令。我检查了我的 PATH 变量，一切似乎都正常。我已经尝试将它们指向 OSGeo4Win 的 32 位和 64 位版本。无论如何，我每次都会得到以下输出：

有人有什么想法吗？
更新：我去商店买了一台新笔记本电脑，但我仍然遇到同样的问题。这可能是某些 GeoDjango 依赖项的版本控制问题吗？我不知所措，但这对我来说有点紧急。

问题最终成为 Django 和 GDAL 之间的版本不匹配。 Django 没有搜索正确的文件名（在我的例子中是
gdal202.dll）。修复它需要我将
str('gdal202')添加到第 26 行的以下文件中：(Python Root)\Lib\site-packages\django\contrib\gis\gdal\libgdal.py请注意，如果您在虚拟环境中工作，那么
Python Root实际上会在任何地方，即：Users\YourName\Envs\project如果这个问题再次出现，您可以查看您的
C:\OSGeo4W\bin目录，找出哪个gdalxxx.dll是 Django 需要搜索的。此外，请确保您使用 的是 32 位版本 的 Python 和 OSGeo4Win。否则，您可能会看到同样的失败。
