Python 在未安装 python 的计算机上使用脚本的 pyinstaller 版本时，脚本未更新文件内容

Question

所以我现在的问题是我写了一个脚本，每次你按下箭头键时都会更新文件中的内容。 该脚本在我的 PC 上运行良好。 我使用 pyinstaller 试图创建脚本的直接独立版本。 现在的问题是脚本似乎没有更新他们的文件，在应用程序的控制台中，它确实表明它正在正确计算分数。 但是在打开文件时它保持在0。文件不是只读的？：有什么想法吗？ 下面的代码：

import os
import time
import threading


from pynput import keyboard

def on_press(key):

    if (key == keyboard.Key.down):
        wR = open("Round Number.txt", "w")
        w1 = open("Team 1 Score.txt", "w")
        w2 = open("Team 2 Score.txt", "w")
        wR.write("1")
        w1.write("0")
        w2.write("0")
        print("All values have been reset")
    
    if (key == keyboard.Key.up):
        r = open("Round Number.txt", "r")
        previousScore = r.read()
        w = open("Round Number.txt", "w")
        newScore = str(int(previousScore) + 1)
        print("Round file has changed to " + newScore)
        w.write(newScore)
        #print(open("Round Number", "r").read())
    
    if (key == keyboard.Key.left):
        r = open("Team 1 Score.txt", "r")
        previousScore = r.read()
        w = open("Team 1 Score.txt", "w")
        newScore = str(int(previousScore) + 10)
        w.write(newScore)
        print("Team 1 now has " + newScore)
        #print(open("Team 1 Score.txt", "r").read())

    if (key == keyboard.Key.right):
        r = open("Team 2 Score.txt", "r")
        previousScore = r.read()
        w = open("Team 2 Score.txt", "w")
        newScore = str(int(previousScore) + 10)
        w.write(newScore)
        print("Team 2 now has " + newScore)
       # print(open("Team 2 Score.txt", "r").read())

def on_release(key):
    pass
    #print('{0} released'.format(
        #key))
    '''if key == keyboard.Key.esc:
        # Stop listener
        return False'''

#Collect events until released
with keyboard.Listener(
        on_press=on_press,
        on_release=on_release) as listener:
    listener.join()

# ...or, in a non-blocking fashion:
listener = keyboard.Listener(
    on_press=on_press,
    on_release=on_release)
listener.start()```

我在您的代码中立即看到的主要错误之一是您在打开文件后没有关闭它们。 我没有直接测试你的代码，但我确实修改了它以with如下。 我测试了它，它工作正常。 我还创建了一个可执行文件，它也可以很好地处理存储在文件中的值。

from pynput import keyboard

def on_press(key):

    if (key == keyboard.Key.down):
        with open("Round Number.txt", "w") as wR:
            wR.write("1")
        with open("Team 1 Score.txt", "w") as w1:
            w1.write("0")       
        with open("Team 2 Score.txt", "w") as w2:
            w2.write("0")

        print("All values have been reset")

    if (key == keyboard.Key.up):
        with open("Round Number.txt", "r") as r:
            previousScore = r.read()
        with open("Round Number.txt", "w") as w:
            newScore = str(int(previousScore) + 1)
            w.write(newScore)

        print("Round file has changed to " + newScore)
    
    if (key == keyboard.Key.left):
        with open("Team 1 Score.txt", "r") as r:
            previousScore = r.read()
        with open("Team 1 Score.txt", "w") as w:
            newScore = str(int(previousScore) + 10)
            w.write(newScore)
        print("Team 1 now has " + newScore)

    if (key == keyboard.Key.right):
        with open("Team 2 Score.txt", "r") as r:
            previousScore = r.read()
        with open("Team 2 Score.txt", "w") as w:
            newScore = str(int(previousScore) + 10)
            w.write(newScore)
        print("Team 2 now has " + newScore)

def on_release(key):
    pass

#Collect events until released
with keyboard.Listener(on_press=on_press,on_release=on_release) as listener:
    listener.join()

# ...or, in a non-blocking fashion:
listener = keyboard.Listener(on_press=on_press,on_release=on_release)
listener.start()

一个主要问题是我必须手动创建 3 个文件，并且在开始时没有按下Down导致程序崩溃。 也尝试解决这个问题。
