Windows10+python3.10 安装geopandas库时，所依赖的fiona库安装失败！

python安装geopandas、fiona包出错：Provide a path to gdal-config using a GDAL_CONFIG environment

下面是报错的代码：

解决办法

1. 下载所需要的whl文件

在网站https://www.lfd.uci.edu/~gohlke/pythonlibs/ 上下载适合自己电脑版本的fiona库的whl文件，我下载了Fiona-8.21-cp310-cp310-win_amd64.whl

2. pip安装

打开windows powershell（管理员)（A）【右键点击屏幕左下角的windows标志，进行选择】，先切换到whl的下载路径（我的是默认了C盘的路径），再pip指令安装即可。

 黄色标注部分即输入的部分

PS C:\WINDOWS\system32> cd C:\Users\Administrator\Downloads

PS C:\Users\Administrator\Downloads> pip install Fiona-1.8.21-cp310-cp310-win_amd64.whl

3. 安装geopandas库

切回cmd，切换到python3.10的目录，执行以下命令：

pip install geopandas -i https://pypi.douban.com/simple/
