title: Errno 2 No such file or directory: 'ffprobe': 'ffprobe'
body: <p>I have to develop an Alexa Skill that use Pydub for edit mp3 file.</p>
  
  <p>Pydub requires ffmpeg and so I have add it in requirements.txt but now, when I try to run my skill, it give me <em>"Sorry, I had trouble doing what you asked. Please try again."</em>.</p>
  
  <p>In CloudWatch the error is: <code>[Errno 2] No such file or directory: 'ffprobe': 'ffprobe'</code> but in requirements.txt there is the ffprobe import.</p>
  
  <p>NB: In local the code runs successfully without any errors</p>
