I am geting constant eror while trying to isntal math3d or urx libary for Python using pip install. I am using Windows 10 and Python 3.7.3

I tried to: - unistall/instal python and also try older version 3.4.4.. nothing work - upgrade setuptools - upgrade pip (then I get even more errors)

Here is my error:
C:\Python34\Scripts>pip install math3d

This tracker is only for issues related to CPython. math3d is not a part of CPython stdlib. I would suggest following up on the respective repo's issue tracker.

In addition to being a third-party library, according to the output you posted, you're actually running Python 3.4 not 3.7.
