麒麟系统安装pyautogui

一.安装pip3

1.直接在terminal中输入python，得到的版本是2.7.12，说明python2.7.12是当前系统默认，[优先级]高于python3.8.2，因为要用python3，所以需要将python3.8设置为默认。

sudo update-alternatives --install /usr/bin/python python /usr/bin/python2 100
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 150

2、python3.8.2安装pip

# 安装pip3
sudo apt-get install python3-pip
# 更新pip3,更新至最新版本的pip3
sudo pip3 install --upgrade pip
# 卸载pip3,安装pip这个指令就不要用了，只是顺便提一下
sudo apt-get remove python3-pip

二.安装pyautogui

sudo apt-get scrot
sudo apt-get install python-tk
pip3 install pyautogui
sudo apt-get install python3-tk python3-dev

三.查看
