不理解错误读取不正确的权限 [英] Don't understand error reading improper permissions

问题描述

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:

I'm trying to make a bot for a game using pyautogui, however when this line of code runs:

    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，我检查了正确文件类型和文件路径正确的图片，此外，我还检查了 png 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这一点

Reading this error I checked that the pictures where both the right file type and that the file path was correct, on top of that I also checked that png is a supported file type for the pyautogui library. Therefore the only problem I can see is that it has improper permissions. My question is therefore if it is so and how I correct it then or how I could check this myself

感谢所有指点！

如果有帮助，这是我的完整代码，然后是完整的错误

推荐答案

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:

Just had the same problem mate and I found a solution that worked for me. What I did was:

import cv2

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