在 Microsoft Windows 操作系统上的 Python 3.6 上使用 GDAL 安装 Fiona 和 Geopandas 失败？

Question

我需要在 Python 3.6 上使用 pip 安装依赖于 Fiona 和 GDAL 的 Geopandas。我已经使用从这里下载的轮文件在 Python 上安装了 GDAL 库。

Processing c:\users\_chena\downloads\gdal-2.4.1-cp36-cp36m-win_amd64.whl
Installing collected packages: GDAL
Successfully installed GDAL-2.4.1

然后我尝试了pip3 install geopandas。我遇到了以下错误：

    Complete output from command python setup.py egg_info:
    A GDAL API version must be specified. Provide a path to gdal-config using a GDAL_CONFIG environment variable or use a GDAL_VERSION environment variable.

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in C:\Users\_chena\A
ppData\Local\Temp\2\pip-install-vy05tre2\fiona\

我找不到 gdal-data 目录所在的任何地方。鉴于这样的错误日志A GDAL API version must be specified. Provide a path to gdal-config using a GDAL_CONFIG environment variable or use a GDAL_VERSION environment variable.，我该如何使用通过 pip3 安装的 Python GDAL 库来设置 GDAL_CONFIG 环境变量？

唯一的解决方案似乎是从这里安装现成的二进制文件 ~gohlke

然后，只需在本地安装所需的库。对我来说，我按这个顺序做了以下（Python 3.8.6）

pip install GDAL-3.1.4-cp38-cp38-win_amd64.whl

pip install Fiona-1.8.18-cp38-cp38-win_amd64.whl

pip install geopandas-0.8.1-py3-none-any.whl
