这是我收到的错误：

PS：这是我和朋友一起设计的游戏

解决方案
问题仅在游戏正在运行(鸟是活的)并且您试图杀死游戏时才会出现。
当您按kill it时，它会运行turtle.bye()，这将删除所有对象并移除窗口，但它不会停止仍要运行move()并绘制对象的ontimer()(但它们不再存在，这会给出消息invalid command name "1771926755840move")。
当您按kill it时，它应该设置变量ie。running = False
def stop():
global running
running = False
应签入move以停止循环并关闭窗口
if running:
# repeate loop and run `move` again
turtle.ontimer(move, 50)
else:
# stop loop and close window
turtle.bye()
#winsound.PlaySound(None, winsound.SND_PURGE)
我的减少了模块的版本。
我创建了自己的类vector，所以我不需要freegames，因为我不知道。
我使用datetime而不是timeit是因为end-start可以直接提供timedelta。
我注释了winsound，因为它只适用于Windows，但我使用的是Linux。
我为paused、unpased添加了代码，它不需要Threading。

坦率地说，如果您使用
tkinter to display buttons then you could use tkinter.Canvasto draw objects, andtkinter.bind()to runtap, and root.after()instead ofontimer()to run loop - and then you don't needturtle`
