SyntaxError: invalid syntax when running supervisor-stdout plugin on Python 3.8 #1434
Description
The problem
I installed supervisor using pip like:
pip install supervisor supervisor-stdout
Installation was succesful. Then trying to open supervisord crashes:
ubuntu:~$ supervisord
Traceback (most recent call last):
