Python 可执行文件（pyinstaller）在我关闭时抛出错误

Question

我在 Windows 上用 Turtle 创建了一个基本的 Pong 游戏，效果很好，但每次我关闭它时，它都会抛出一个错误：'Fatal error detected: Failed to execute script pong'。在寻求帮助之前，我一直在寻找解决方案，但我找不到合适的答案。

为了创建 .exe 文件，我使用了“pyinstaller”。这是我写的确切命令：

pyinstaller --onefile --windowed --add-data "bounce.wav;." --add-data "collision.wav;." --add-data "score.wav;." pong.py

这是我的代码：

"""

import turtle
import winsound

import os
import sys

win = turtle.Screen()
win.title("Pong")
win.bgcolor("black")
win.setup(width=800, height=600)
win.tracer(0)

# Score
score_a = 0
score_b = 0

# Paddle A
paddle_a = turtle.Turtle()
name_a = "Verde"
paddle_a.speed(0)
paddle_a.shape("square")
paddle_a.color("green")
paddle_a.shapesize(stretch_wid=5, stretch_len=1)
paddle_a.penup()
paddle_a.goto(-350, 0)

# Paddle B
paddle_b = turtle.Turtle()
name_b = "Amarillo"
paddle_b.speed(0)
paddle_b.shape("square")
paddle_b.color("yellow")
paddle_b.shapesize(stretch_wid=5, stretch_len=1)
paddle_b.penup()
paddle_b.goto(350, 0)

# Ball
ball = turtle.Turtle()
ball.speed(0)
ball.shape("circle")
ball.color("white")
ball.penup()
ball.goto(0, 0)
ball.dx = 0.15
ball.dy = -0.15

# Pen

我不知道是什么导致了这个错误，因为程序运行良好并且所有音效都正常工作。

谢谢大家的回答！

嘿，不确定您是否还需要这方面的帮助，但第 103 行似乎引起了问题：

ball.setx(ball.xcor() + ball.dx)

它只发生在关闭应用程序时，就像你说的那样。 我不确定是否有合适的解决方案，但可以用来避免 pyinstaller 引发错误的创可贴解决方案是将整个 while 循环包装在 try/catch 中。

# Main game loop
try:
    while True:
        win.update()

        # Move the ball
        ball.setx(ball.xcor() + ball.dx)
        ball.sety(ball.ycor() + ball.dy)

        # Border checking
        if ball.ycor() > 290:
            winsound.PlaySound(resource_path("bounce.wav"), winsound.SND_ASYNC)
            ball.sety(290)
            ball.dy *= -1

        if ball.ycor() < -290:
            winsound.PlaySound(resource_path("bounce.wav"), winsound.SND_ASYNC)
            ball.sety(-290)
            ball.dy *= -1

        if ball.xcor() > 390:
            winsound.PlaySound(resource_path("score.wav"), winsound.SND_ASYNC)
            ball.goto(0, 0)
            ball.dx *= -1
            score_a += 1
            pen.clear()
            pen.write("{} {} | {} {}".format(name_a, score_a, score_b, name_b), align="center", font=("Courier", 24, "normal"))

        if ball.xcor() < -390:
            winsound.PlaySound(resource_path("score.wav"), winsound.SND_ASYNC)
            ball.goto(0, 0)
            ball.dx *= -1
            score_b += 1
            pen.clear()
            pen.write("{} {} | {} {}".format(name_a, score_a, score_b, name_b), align="center", font=("Courier", 24, "normal"))

        # Paddle and ball collisions
        if (ball.xcor() > 340 and ball.xcor() < 350) and (ball.ycor() < paddle_b.ycor() + 50 and ball.ycor() > paddle_b.ycor() - 50):
            winsound.PlaySound(resource_path("collision.wav"), winsound.SND_ASYNC)
            ball.setx(340)
            ball.dx *= -1

        if (ball.xcor() < -340 and ball.xcor() > -350) and (ball.ycor() < paddle_a.ycor() + 50 and ball.ycor() > paddle_a.ycor() - 50):
            winsound.PlaySound(resource_path("collision.wav"), winsound.SND_ASYNC)
            ball.setx(-340)
            ball.dx *= -1
except Exception:
    sys.exit(0)

我承认这不是最好的解决方案，但我希望这会有所帮助！
