Installation pylinac using pip - deprecation warning Python 2.7.18 & pip 19.3.1

Hello All,

I’m looking for help installing. pylinac on Windows 10 Pro (x64) with Anaconda 3, 2021.05, x86_64.

I was able to install pylinac on a personal PC at home and after delay over a course of months with permissions with IT, began installation with a department PC using the same approach.

My process/approach was:
Anaconda with Python 3
then using commandline, created virtual environment using python 2.7.18 (which installs pip 19.3.1). This I’m sure worked with my PC at home.
However, when running pip on my work PC, it gives me a warning and error messages:

Collecting pylinac

Hi James,
Pylinac has not supported python 2 for a long time. I would try creating a new venv with python 3.6+ and then try again. Let us know if you still have trouble.

Thank you!
It’s running. (Python 3.8.8)

Not sure why I thought I read something about Python(x,y) not working on Python 3 and thought it was necessary to run on an older version.

Thanks again!
