Hi guys,

I'm trying to run a python script that requires yfinance.  This is the error I'm getting:

$ pip3 install yfinance

I thought about subing in Linux for the uname but I want something that is more  general.  This must have happened before. Is there a way to search the cygwin mail archives?  Delorie seems to out of commission.


What should I do?


TIA.

Cygwin Fan.
