python - 当我使用 crontab 在启动时运行 python 文件时，出现以下错误

问题描述

我安装了以下软件包，已经 sudo pip3 install pyautogui。并在 crontab 中完成以下设置，@reboot XAUTHORITY=/home/pi/.Xauthority DISPLAY=:0 sh /home/pi/ICUmedical/launcher.sh >/home/pi/logs/cronlog 2>&1;

Traceback (most recent call last):
File "main.py", line 5, in <module>
import pyautogui as ui
File "/usr/local/lib/python3.7/dist-packages/pyautogui/__init__.py", line 241, in <module>

_display = Display(os.environ['DISPLAY'])
