{:5_102:}解决啦，方法是在pygame.quit()后面加入sys.exit()就可以了
，执行pygame.quit(),只是让程序让程序缓存清空了下，实际上程序还在运行，导致后面调用pygame的东西的时候就会报错
这是小甲鱼pygame第一个游戏，相关图片音频资源是小甲鱼那里提供的，可以直接创建个同名的文件先运行试试看哈 测试发现，line190 和line259 pygame.quit()导致的问题
如果注释掉，是不会报错的，小甲鱼也用了这个，说是在idle能正常退出，运行小甲鱼的没问题 在每个pygame.quit()后面加上raise SystemExit
最后变成 try:
main()
except Exception:
traceback.print_exc()
pygame.quit()
input()
emm，都解决啦，尴尬
