Seems that this specific error message was caused by Eclipse PyDev tricks. I still don't understand where this Python36 comes from -- the frontend used Python 3.7 and backend its venv.

With pure python the problem was not being able to import parso. The problem applies only to Thonny 2.1 which copies jedi for the back-end but I forgot to copy parso for newer versions.
