我收到此错误：

追踪（最近一次通话）： pygame.display.update（）错误：视频系统未初始化我是一个pygame菜鸟，不知道如何解决这个请帮忙！

我现在只是添加一个句子，所以它会让我提交post.dsijklasdvjnkjdlsnv ksdjvkjkjsndlknsdva kksajsdjdvkjlkvnsddlkvndk。 sddvjvkdsvnlskdkdsjvjkvv skdvkvjnskjv

我认为你的意思是当你退出游戏时会出现这个错误。 pygame.quit()取消初始化所有pygame模块，但while循环仍然保持运行，当调用pygame.display.update()时，视频系统不再被初始化并导致错误。要解决这个问题，请执行以下操作：

running = True

while running:
    for event in pygame.event.get():
        if event.type == QUIT:
            running = False

    # Game code ...

# After the while loop is done, uninitialize pygame and exit the program.
pygame.quit()
sys.exit()  # import sys at the top of the module.
