Failed building wheel for grpcio

[rperdon]

windows 10 machine
python 3.7.0
Current version of setuptools was 68.0.0

Tried installing recommended version 40.7.1 as per readme
pip --upgrade setuptools==47.1.0

Same error

The error out message is long, but seems to be an issue with the VC tools version?

Hey,

Python 3.7.x has reached its EOL last month [https://devguide.python.org/versions/], I wouldn't recommend using that Python version anymore.

I'm super unfamiliar with Visual Studio builds on Windows, could you lay down what you've tried and your current setup?

Close this, I solved it. After I had swapped python versions, I forgot to redo the requirements software versions in the requirements text.
