fb-prophet python package installation failed with exit status 2

Question

I have a typical issue installing fbprophet package on Windows with pip. Now it's something else.

Here're my specs:

• Windows Server 2019 64-bit OS, x64-based processor
• AMD EPYC 75020 32-Core Processor
• Python 3.9.10
• pip 22.0.2 from C:\Users\Administrator\AppData\Local\Programs\Python\Python39\lib\site-packages\pip (python 3.9)
• installed the latest Microsoft C++ Build Tools from here https://visualstudio.microsoft.com/visual-cpp-build-tools/

Tried installing like

pip install fbprophet --user AND also without --user
