运行“import pyautogui”时抛出此错误
我运行以下命令 -
pip install `python3-xlib`
sudo apt-get install scrot
sudo apt-get install python3-tk
sudo apt-get install python3-dev
pip install pyautogui
您必须正确设置环境变量DISPLAY。它应该由您的操作系统定义。如果不是，您可以手动定义它。
Option 1- 运行 python：
DISPLAY=:0 python
Option 2- 在Python中设置环境变量
import os
os.environ['DISPLAY'] = ':0'
Option 3- 给你.bashrc file
echo "DISPLAY=:0" >> ~/.bashrc
source ~/.bashrc
