KeyError: 'DISPLAY' when installing pyautogui

When I tried to install pyautogui with sudo pip3 install pyautogui I get the error info

I followed the install steps listed in the Docs(http://pyautogui.readthedocs.io/en/latest/install.html). Do anyone know why this happens and how to fix it? Thank you so much.

Have solved it. It is because of using ssh to install the package. When I install it by using the raspberrypi directly it solved.

Hello,

I do a mouse-reset.py like this for my magic mirror:

#!/usr/bin/python3
# -*- coding: utf-8 -*-

import pyautogui
import time

while True:
    try:
        if pyautogui.position != (1918, 1078):
            time.sleep(0.1)
            pyautogui.moveTo(1918, 1078)
            time.sleep(0.1)
        time.sleep(0.1)
    except:
        time.sleep(0.1)

it’s work correctly when the mirror boot. but i need to pkill python when i want to power off the screen.

my problem: i can’t laucnh this in SSH: python3 /home/pi/programmes/mouse-reset.py

i have error display.

pyautogui test the client but not serveur display.

What i have to do to do this python program in SSH?

i test add it in a mouse.sh and do: bash /home/pi/scripts/mouse.sh but same problem: Error Display.

Please, i need help to activate this python program with SSH when i do bash /home/pi/scripts/ecran_on.sh

i want this program execute in ssh serveur, not in ssh client.

thank you for your help.
