I'm running into an issue getting webrtc from Chromium set up and building locally. When running gclient sync, I get the following error:

This is on Mac. I can download the tar.xz's just fine, but for some reason the script fails on this portion. python --version returns 2.7.16, though I've also tried it with python aliased to python3 as well.
It looks like webrtc for android can only be built on Linux, and that's why gclient sync / install build tools is not working on MacOS.
