问题描述

I'm trying to install "supplychainpy" package for python but i get a gcc error. "error: command 'gcc' failed with exit status 1"

This does not help. This is the output i get:

解决方案

问题可能是 gcc 编译器配置。您可以从https://pypi.org/project/supplychainpy/#files下载编译后的.whl 文件。请注意，文件适用于 macosx。*-macosx_10_6_x86_64.whl
