我是 python 新手，我正在使用pydub模块来播放 mp3 曲目。

这是我播放 mp3 的简单代码：

#Let's play some mp3 files using python!

from pydub import AudioSegment
from pydub.playback import play

song = AudioSegment.from_mp3("/media/rajendra/0C86E11786E10256/05_I_Like_It_Rough.mp3")
play(song)

当我运行这个程序时，它说：

*/usr/bin/python3.4 /home/rajendra/PycharmProjects/pythonProject5/myProgram.py
/usr/local/lib/python3.4/dist-packages/pydub/utils.py:161: RuntimeWarning: Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work
  warn("Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work", RuntimeWarning)

    return cls.from_file(file, 'mp3')

    raise child_exception_type(errno_num, err_msg)
FileNotFoundError: [Errno 2] No such file or directory: 'ffmpeg'

Process finished with exit code 1*

请帮我！我已经检查了所有路径，但它不起作用。我目前正在使用 Ubuntu。

帮助将不胜感激！

就像警告说的那样：

Couldn't find ffplay or avplay - defaulting to ffplay, but may not work

你需要要么ffplay要么avplay; 然而ffplay是指ffmpeg在最近的版本中不能在 Ubuntu 中安装。安装libav-tools包apt-get：

sudo apt-get install libav-tools

好像你需要ffmpeg，但是

sudo apt-get install ffmpeg

不再工作了。您可以通过以下方式获取 ffmpeg：

sudo add-apt-repository ppa:jon-severinsson/ffmpeg
sudo apt-get update
sudo apt-get install ffmpeg

我在我的 Ubuntu Ubuntu 18.04.3 LTS 上遇到了同样的问题。

只需使用以下方法安装 ffmpeg 即可解决该问题：

sudo apt-get install ffmpeg

而不是流行的 Git 线程（https://github.com/lengstrom/fast-style-transfer/issues/129）建议：

brew install ffmpeg

但是，如果一个不起作用，您可以随时尝试两者。

如果它不允许您使用安装， sudo apt-get install libav-tools您可以从此处下载 .deb：

wget http://launchpadlibrarian.net/339874908/libav-tools_3.3.4-2_all.deb

然后运行sudo apt install ./libav-tools_3.3.4.2_all.deb
