python的pyautogui模块的小问题，是我环境配置出错了吗？

Question

import pyautogui

img = pyautogui.screenshot()
color = img.getpixel((100,100))

报错如下，提示第三行出错
raise PyScreezeException('The Pillow package is required to use this function.')
pyscreeze.PyScreezeException: The Pillow package is required to use this function.
这是什么情况呢

Answer 1

pillow版本不对，重装一下
