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!
