文章背景：最近在学习pyautogui模块中的处理屏幕，想要通过运行python代码，获取鼠标光标处像素的RGB颜色值。python代码如下：

# from the book: Automate the Boring Stuff with Python
import pyautogui
pyautogui.pause = 1
pyautogui.failsafe = True

print('Press Ctrl-C to quit.')
try:
    while True:
        # Get and print the mouse coordinates.
        x, y = pyautogui.position()
        positionStr = 'X: ' + str(x).rjust(4) + ' Y: ' + str(y).rjust(4)
        
        pixelColor = pyautogui.screenshot().getpixel((x,y))
        positionStr += ' RGB: (' + str(pixelColor[0]).rjust(3)
        positionStr += ', ' + str(pixelColor[1]).rjust(3)
        positionStr += ', ' + str(pixelColor[2]).rjust(3) + ')'
        print(positionStr,end = '')
        print('\b'*len(positionStr),end='',flush = True)
except KeyboardInterrupt:
    print('\nDone.')

代码运行时，程序报错。pyscreeze.PyScreezeException: The Pillow package is required to use this function.

检查电脑上的pyllow模块，目前是6.2.0版本，还不是最新版本，考虑升级pyllow模块。我的电脑环境是：win10+py3.7+anaconda3。在Anaconda3的Prompt上运行如下代码：

pip install -i https://pypi.doubanio.com/simple/ --trusted-host pypi.doubanio.com pillow
