node.js : fluent-ffmpeg throws error when converting mp4 to mp3

I'm trying to convert an mp4 video to mp3 with node's fluent-ffmpeg module. Here is my code:

ffmpeg = require 'fluent-ffmpeg'

mp4 = '/Users/jashua/Desktop/video.mp4'
mp3 = '/Users/jashua/Desktop/audio.mp3'

proc = new ffmpeg({source:mp4})
    .toFormat('mp3')
    .setFfMpegPath('/Applications/ffmpeg')
    .saveToFile(mp3, (stdout, stderr)->
            return console.log stderr if err?
            return console.log 'done'
        )

On running it, I get the following error:

TypeError: Cannot call method 'saveToFile' of undefined
at Object.<anonymous> (/Users/jashua/Desktop/ytdl.coffee:10:12, <js>:18:60)
  at Object.<anonymous> (/Users/jashua/Desktop/ytdl.coffee:1:1, <js>:25:4)
  at Module._compile (module.js:456:26)

Any ideas?

Solution: 

proc = new ffmpeg({source:mp4})
    proc.setFfMpegPath('/Applications/ffmpeg')
    proc.saveToFile(mp3, (stdout, stderr)->
                return console.log stderr if err?
                return console.log 'done'
            )
    enter code here

For anyone else coming across this and experiencing the same issue I was .setFfmpegPath() requires the full path including the binary not just the directory the binary is in.

the spawn system call ends with error ENOENT if the program cannot be found. In this case, ffmpeg is not found, so you have to tell it where it is:

proc = new ffmpeg({source:mp4})
    .setFfmpegPath("wherever ffmpeg is installed ") <-- this is the new line
    .toFormat('mp3')
    .saveToFile(mp3, (stdout, stderr)->
            return console.log stderr if err?
            return console.log 'done'
        )
