FileNotFoundError：[Errno 2]没有这样的文件或目录：'ffmpeg'
问题描述：
我是新的蟒蛇，我使用pydub模块来播放MP3曲目。FileNotFoundError：[Errno 2]没有这样的文件或目录：'ffmpeg'
这里是我的简单的代码来播放MP3：
#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，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

请帮帮我！我已检查过所有路径，但无法正常工作。我目前正在使用Ubuntu。
帮助，将不胜感激！

像警告说：
Couldn't find ffplay or avplay - defaulting to ffplay, but may not work
您必须要么ffplay或avplay;但是ffplay指的是ffmpeg，它在最近的版本中不能在Ubuntu中安装。与apt-get安装libav-tools包：
sudo apt-get install libav-tools
+0
和'ffmpeg'应该再次可用 – 2017-01-21 05:10:56

好像你需要的ffmpeg，但
sudo apt-get install ffmpeg
不工作了。您可以通过获得的ffmpeg：
sudo add-apt-repository ppa:jon-severinsson/ffmpeg
sudo apt-get update
sudo apt-get install ffmpeg
Ubuntu的值不一定有** **的ffmpeg甚至在仓库命令 – 2015-04-05 05:20:16
