pygame.error: 视频系统未初始化.pygame.init() 已经调用 [英] pygame.error: video system not initialized. pygame.init() already called

问题描述

这几乎是您可以在 pygame 中编写的最简单的代码.它所做的只是创建一个窗口并允许您关闭它.但是，我收到此错误pygame.error: 视频系统未初始化.我在网上搜索了这个，似乎大多数人忘记调用 pygame.init().我不确定为什么会收到此错误.

This is pretty much the simplest code you can make in pygame. All it does is create a window and allow you to close it. However, I am getting this error pygame.error: video system not initialized. I searched online for this and it seems most people forget to call pygame.init(). I am not sure why I am getting this error.

import pygame
pygame.init()
screen = pygame.display.set_mode((900,500))
while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()

推荐答案

只需添加 sys.exit(0) 和结尾就完成了

Just add sys.exit(0) and the end and you are done

以下是官方文档中的一些信息

Here is some info from official document

pygame.quit() 取消初始化所有 pygame 模块 quit() -> 无取消初始化之前已初始化的所有 pygame 模块.当 Python 解释器关闭时，调用此方法无论如何，所以你的程序不应该需要它，除非它想要终止其 pygame 资源并继续.打电话是安全的多次调用此函数:重复调用无效.

pygame.quit() uninitialize all pygame modules quit() -> None Uninitialize all pygame modules that have previously been initialized. When the Python interpreter shuts down, this method is called regardless, so your program should not need it, except when it wants to terminate its pygame resources and continue. It is safe to call this function more than once: repeated calls have no effect.

注意，pygame.quit()uninitialize 所有 pygame 模块不会退出你的程序.考虑让你的程序以同样的方式结束正常的python程序会结束.

Note, that pygame.quit()uninitialize all pygame modules will not exit your program. Consider letting your program end in the same way a normal python program will end.

这是给您的示例代码.

import pygame
import sys
pygame.init()
pygame.display.set_mode((900, 500 ) )


while True :
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                sys.exit(0)
