Microsoft C++ Build tool required to install fabric - Python

问题

I'm trying to install fabric via pip install fabric in order to deploy a flask app on a server.

I have the following error :

I was facing the exact issue when installing Apache-Airflow, after searching on the google found below Microsoft forum.
