【问题描述】：

我正在尝试制作 DAW，但每当我尝试运行代码时，都会遇到相同的错误。即使我输入了正确的路径，也找不到我的文件。代码：

import getpass
from pydub import AudioSegment
username=getpass.getuser()
song=AudioSegment.from_mp3('C:\\Users\\sanch\\Documents\\Cryo DAW\\bad_patty!.mp3')

错误：

    warn("Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work", RuntimeWarning)

请帮忙！

【问题讨论】：

找不到的不是您的音频文件，而是ffmpeg。该模块是ffmpeg 工具的薄包装，您显然没有。您需要安装ffmpeg，并且可能需要告诉模块在哪里可以找到它。

【解决方案1】：

如果您在 Linux 上，只需安装 ffmpeg 和 libavcodec-extra：
- ```
$ sudo apt-get install ffmpeg libavcodec-extra
```
然后安装 pydub 库，您的错误将得到修复：
- ```
$ pip3 install pydub
```
