    During handling of the above exception, another exception occurred:

Command "python setup.py egg_info" failed with error code 1 in C:\Users\AVIMAT~1\AppData\Local\Temp\pip-install-hnb_xdmp\pyproj\

我已经尝试了很多其他方法，比如升级 setuptools 或下载 Fiona 和 GDAL 二进制文件，但它们似乎都不起作用。

Answer 1

正如 Traceback 所说：下载这个

https://visualstudio.microsoft.com/downloads/

这将为您提供正在安装的库所需的 C++ 库

Answer 2

问题在于编译pyproj 。 尝试从https://www.lfd.uci.edu/~gohlke/pythonlibs/#pyproj安装预编译的二进制文件

Answer 3

这帮助了我

pip install wheel
pip install pipwin

pipwin install numpy
pipwin install pandas
pipwin install shapely
pipwin install gdal
pipwin install fiona
pipwin install pyproj
pipwin install six
pipwin install rtree
pipwin install geopandas
