Installation fails. - Githubissues

Describe the bug Installing Mylar using the readme installation instruction results in a few errors. Initially I thought this was because it was using an older version of python, so I unintalled all other versions of python and installed 3.8.1 since it was mentioned in the readme. I still got exceptions when installing, which mention microst visual studio 14, which I installed. Trying pip38 and py install command result in errors. I got stuck at my current error message, though it could just be brain fatigue and something obvious. I apologise if this is something silly/PMAC related.
Screenshots/Logs I didn't find a log file. The posted log is only of the error message and the last line of succesful for brevity. I can add it all if needed. I'm not sure where the logs the last line of the error refers to.
