Issues when using inquirer JS (subscribe event)

[Truemedia]

Hi there,
Iv'e been working on a slush generator for a while, and being go well for past year or so thanks 👍

The problem I have run into now is I am trying to take advantage of some of the reactive functionality of inquirer JS by doing observable questions.

inquirer.prompt( Rx.Observable.fromArray( questions ); ).process.subscribe(
  onEachAnswer,
  onError,
  onComplete
);

I seem to be running into this problem, which from what I know is a core part of gulp (3 at least)

node_modules/orchestrator/index.js:153
TypeError: Cannot read property 'subscribe' of undefined

This is the first time Iv'e attempted messing with async in inquirer so not sure how to get this working, and was suprised that I could not find anyone with similar situation already.

Any ideas anyone?
