[Resolved] ESPHome devices will not compile after updating to core-2021.12.1

I have HA running on a Raspberry PI 4, I am not running it in a container. I configured a Sonoff S31 smart plug in ESPHome and flashed it a couple weeks ago by plugging into the PI directly. Everything worked great. Today I wanted to update HA to the latest and then I checked on ESPHome. I see there are updates so I figured I update my devices wirelessly this time.

When I try to update the plug I get the below errors in the log. I am at a loss here. Am I missing Python on my core OS (System Health says the version there)? How do I correct this?

I was able to resolve the issue by uninstalling ESPHome and then reinstalling it. Not sure why this happened in the first place.

Note, I exported all my YMAL config files and did a backup first but when in reinstalled I did not have to recreate the YAMAL files, they all came back and the devices connected right away.

I hope this helps someone else.

Had the same issue. Seems to be data stored outside of venv.
To get the storage location
pip freeze | grep platformio
