Could not find a version that satisfies the requirement fastapi (from versions: ) No matching distribution found for fastapi

I was getting the following while trying to install FastAPI. The issue was I had two Python versions installed in my system and I was trying to install it using pip from Python2.7.

Once I tried to install using Python3.9 it worked fine.

C:\Users\Jay>C:\Users\Jay\AppData\Local\Programs\Python\Python39\Scripts\pip.exe install fastapi
