Getting "WARNING (aesara.configdefaults): g++ not available," on fresh PyMC4 install

So, after looking at these instructions, I realized I was creating the environment on top of a minimal Miniconda install. So, I pulled down the installer for the full Anaconda (2022.05, Windows 64 bit) and did a clean install and now it imports without warnings:

I don’t know how using the full Anaconda distribution solves the problem, but it seems to work. Thanks!
