Issue with Python

Hello! I am a Python programmer and I love the language. However, I
installed Python 3.9 and suddenly, pip does not install Python libraries
anymore. It says that I need Visual Studio C++ 2014 and exits with:
"ERROR: Command errored out with exit status 1:..error: Microsoft Visual
C++ 14.0 is required. Get it with "Build Tools for Visual Studio":
https://visualstudio.microsoft.com/downloads/"
(The complete output is about 302 lines long. I will attach at the end of
the email.)
But I never needed Visual C++ 14 to install modules. Plus I have a bunch of
C++ redistributables (but not 14). Is there any thing I can do to fix this?
Also, is there any way to carry over my libraries and modules from my
previous Python installation (Python 3.8.5)? Or do I need to manually
reinstall them?
Thank you for your help. Python is awesome!
