python - 当我尝试查找像素颜色时，pyautogui 出现故障，但有时当我什至不更改代码时它也可以工作

Question

我制作的简单钢琴瓷砖机器人，它曾经工作，但最近停止工作，当我运行它时，我收到一个错误，但有几次我运行完全相同的东西，它工作得很好。

from pyautogui import *
import pyautogui
import time
import keyboard
import random
import win32api, win32con

def click(x, y):
    win32api.SetCursorPos((x, y))
    win32api.mouse_event(win32con.MOUSEEVENTF_LEFTDOWN, 0, 0)
    time.sleep(0.05)  
    win32api.mouse_event(win32con.MOUSEEVENTF_LEFTUP, 0, 0)


while keyboard.is_pressed('q') == False:

    if pyautogui.pixel(480, 280)[0] == 0:
        click(480, 280)
    if pyautogui.pixel(550, 280)[0] == 0:
        click(550, 280)
    if pyautogui.pixel(620, 280)[0] == 0:
        click(620, 280)
    if pyautogui.pixel(688, 280)[0] == 0:
        click(688, 280)

当我尝试运行它时弹出的错误：

Traceback (most recent call last):

    if pyautogui.pixel(550, 280)[0] == 0:

    raise WindowsError("windll.user32.ReleaseDC failed : return 0")
OSError: windll.user32.ReleaseDC failed : return 0

Process finished with exit code 1
