pip install playsound安装报错，pip install flask正常，求解决以播放MP3

问题说明 #

执行pip install playsound时出现构建wheel失败的错误，核心报错为OSError: could not get source code，但pip install flask可正常运行，目标是用playsound播放MP3文件。完整报错信息如下：

PS D:\100 day python> pip install playsound

原因分析 #

1. 使用的是微软商店版本的Python，该版本源码受系统权限限制，导致inspect.getsource无法读取源码，而playsound 1.3.0的安装脚本依赖此功能。
2. playsound 1.3.0版本的构建脚本存在兼容性问题，不支持Python 3.11及微软商店版Python。

解决方法 #

方法一：安装兼容版本的playsound #

直接指定安装1.2.2版本，该版本安装脚本不依赖inspect.getsource，兼容性更好：

pip install playsound==1.2.2

方法二：替换Python版本 #

卸载微软商店版Python，安装官方版Python（勾选"Add Python to PATH"选项），之后重新执行pip install playsound即可。

方法三：使用替代库播放MP3 #

如果上述方法无效，可换用更稳定的音频库如pygame：

1. 安装pygame：

pip install pygame

2. 播放MP3的示例代码：

import pygame
pygame.mixer.init()
pygame.mixer.music.load("你的MP3文件路径.mp3")
pygame.mixer.music.play()
while pygame.mixer.music.get_busy():
    continue
