这个错误是什么问题，我自学PYautogui。
C:\Python311\python.exe C:\Users\wjj\Desktop\pythonProject\main.py
Traceback (most recent call last):

screenshotIm = screenshot(region=None) # the locateAll() function must handle cropping to return accurate coordinates, so don't pass a region here.
^^^^^^^^^^^^^^^^^^^^^^^

raise PyScreezeException('The Pillow package is required to use this function.')
pyscreeze.PyScreezeException: The Pillow package is required to use this function.
这个错误提示是说你需要安装 Pillow 包才能使用 pyscreeze 库中的 locateOnScreen() 函数。Pillow 是一个 Python 图像处理库，可以用来对图像进行读取、处理和保存等操作。你可以通过以下命令来安装 Pillow：
pip install Pillow
安装完成后，再次运行你的代码即可。
不知道你这个问题是否已经解决, 如果还没有解决的话:
