我以前这样做过十几次，但这次有些东西不工作..

遵循文档:

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:

有没有人有什么想法？

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。

最佳答案

问题最终变成了 version mismatch between Django and GDAL . 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 根目录)\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 实际上会在任何位置，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 Django 需要搜索的 gdalxxx.dll。

此外，请确保您使用的是 32 位版本 Python 和 OSGeo4Win。否则，您可能会看到同样的失败。
