播放声音文件时出现 Python 3 权限错误（mp3，playsound 模块）

Question

该程序几天前运行良好，今天刚刚停止。 没有一个字母被改变。 我的故障排除步骤之一是删除文件“output1.mp3”并检查它是否可以那样工作，但它没有。 另一件事是，当它没有打印出错误时，它会继续播放这个声音文件，无论它是否说正确...这是我得到的最新错误，希望它有所帮助：

Traceback (most recent call last):
  File "main3.py", line 123, in <module>
    start()
  File "main3.py", line 117, in start
    tts(say)
  File "main3.py", line 24, in tts
    play('output1.mp3')

这是我使用的代码，如果您需要我为您提供更多信息，请发表评论：

语音合成器是Amazon Polly 。 顺便说一句，我使用 PyCharm 作为 IDE 并在 Windows 10 上工作。当我切换到我的 linux 机器时，语音识别部分中断了......

更新：我正在稍微调整代码并设法修复 pyaudio 错误，但我在此过程中遇到了另一个错误，这次是关于权限..这是错误日志：

Traceback (most recent call last):
  File "C:/Users/Despot/Desktop/DAv3/main3.py", line 123, in <module>
    start()
  File "C:/Users/Despot/Desktop/DAv3/main3.py", line 118, in start
    ai()

    with open('output11.mp3', 'wb') as f:
PermissionError: [Errno 13] Permission denied: 'output11.mp3'

更新 2 ：我一直在讨论，我发现这个问题只存在于我的 Windows 10 机器上，该程序在 linux 上运行良好。

Answer 1

尝试使用音频文件的绝对路径（完整路径）而不是相对路径。

例如：“C:/Users/Adam/Desktop/dolphin.wav”而不是“dolphin.wav”

这对我有用。

Answer 2

Playsound 库中有一个 windows 目录。 如果这仅在 Linux 上失败，您应该在 linux 机器上安装 playsound lib，然后只将 main3.py 复制到它。

Answer 3

UPDATE2 的答案：将 output11.mp3 复制到另一个位置并将路径更改为新位置：

with open('CHANGE-THIS-PATH', 'wb') as f:

还要确保 python 以管理员身份运行。

Answer 4

在我开始学习 Playsound 软件包时，我遇到了类似的问题。 我正要运行 playsound 代码的基本第一步，即，

from playsound import playsound

playsound('sample.wav')

注意：sample.wav 是我要播放的音频文件。

我试图运行它，但我遇到了与您之前遇到的相同的错误。 几分钟后，我将音频文件从 sample.wav 重命名为 sample，然后将其作为 playsound('sample.wav') 运行

幸运的是！它跑了。 然后我才知道以前它是存储为 sample.wav.wav

因此，让我们将您的音频文件名保留为 output.wav 并尝试将您的音频文件作为 playsound('output.wav.wav') 运行，或者将其重命名为 output 并作为 playsound('output.wav') 运行，对于其他音频格式也是如此也。

希望你得到你的答案！

Answer 5

我通过将 .py 和 .wav 文件移动到文件系统内部不太深的文件夹来解决这个问题。
