MACOS python package installation problem

Question

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

• Yes, I have installed the xcode devtools xcode-select --install
• Yes, I'm sure gcc is present gcc --version
• Yes, my pip is up to date pip install --upgrade pip
• Yes, I have gcc installed (with brew install gcc ).
• Yes i have anaconda package installed with all the dependancies.

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

The problem may be the gcc compiler config. You can download the compiled .whl file from https://pypi.org/project/supplychainpy/#files . Note that *-macosx_10_6_x86_64.whl files are for macosx.
