Unhandled 'error' event

can you tell me what im doing wrong?

> var player = require('play');

> player.sound('./noti.wav')

it says:

> playing=>./noti.wav
> events.js:160
> throw er; // Unhandled 'error' event
> ^

> Error: spawn afplay ENOENT
> at exports._errnoException (util.js:1020:11)
> at Process.ChildProcess._handle.onexit (internal/child_process.js:197:32)
> at onErrorNT (internal/child_process.js:376:16)
> at _combinedTickCallback (internal/process/next_tick.js:80:11)
> at process._tickCallback (internal/process/next_tick.js:104:9)

or is it a bug?

Start by examining the play module's sound entry point and how it launches afplay, using the reported spawn afplay ENOENT trace as the initial clue. Determine whether the missing executable or the unhandled error event is the project behavior to address; done should include a reproducible diagnosis and a confirmed expected outcome.
