python - 不理解错误读取不正确的权限

Question

我正在尝试使用 pyautogui 为游戏制作机器人，但是当这行代码运行时:

    if py.locateOnScreen(r"C:\Users\molta\Documents\Pythons\Poison.png")!=None:

它返回此错误:

OSError: Failed to read C:\Users\molta\Documents\Pythons\Poison.png because file is missing, has improper permissions, or is an unsupported or invalid format

阅读此错误时，我检查了正确的文件类型和文件路径是否正确的图片，此外，我还检查了 png 是否是 pyautogui 库支持的文件类型。因此，我能看到的唯一问题是它的权限不正确。因此，我的问题是，如果是这样，我如何纠正它，或者我如何自己检查

所有指针表示赞赏!

如果有帮助，这是我的完整代码，然后是完整的错误

import pyautogui as py

    if py.locateOnScreen(r"C:\Users\molta\Documents\Pythons\Poison.png")!=None:

刚刚遇到了同样的问题，我找到了一个对我有用的解决方案。
我所做的是:

import cv2

img = cv2.imread(r"path") 
y = pyautogui.locateOnScreen(img)
print(y)
