I have a python code, using gpiozero. When running this code on a RPI-ZEROW it fails, while running same code on RPI3 it succeeds. All installed pretty much the same ( shown checks below ), pigpio is at it last version and located in same directories:
relevant part of code ( error comes from line-2):
from gpiozero import Button, OutputDevice
from gpiozero.pins.pigpio import PiGPIOFactory <-- This line
from sys import platform, path
import time
on RPI ZEROW:
