FileNotFoundError：[Errno 2]沒有這樣的文件或目錄：'ffmpeg'

我是新的蟒蛇，我使用pydub模塊來播放MP3曲目。FileNotFoundError：[Errno 2]沒有這樣的文件或目錄：'ffmpeg'

這裏是我的簡單的代碼來播放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)

當我運行這個程序，它說：

*/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

    return cls.from_file(file, 'mp3') 
    File "/usr/local/lib/python3.4/dist-packages/pydub/audio_segment.py", line 339, in from_file 
    retcode = subprocess.call(convertion_command, stderr=open(os.devnull))

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

請幫幫我！我已檢查過所有路徑，但無法正常工作。我目前正在使用Ubuntu。

幫助，將不勝感激！

Ubuntu的值不一定有** **的ffmpeg甚至在倉庫命令 – 2015-04-05 05:20:16

像警告說：

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

您必須要麼ffplay或avplay;但是ffplay指的是ffmpeg，它在最近的版本中不能在Ubuntu中安裝。與apt-get安裝libav-tools包：

sudo apt-get install libav-tools

和'ffmpeg'應該再次可用 – 2017-01-21 05:10:56

好像你需要的ffmpeg，但

sudo apt-get install ffmpeg

不工作了。您可以通過獲得的ffmpeg：

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