Cannot Initialize?

[dmr07]

Fairly new to imagemin, using it with Gulp. Got error below.
#57 I reinstalled all my app's dependencies again. Still running into same error.

Node: 4.2.1
npm: 2.14.7

Running inside Vagrant, used command "npm run gulp". Did not include imagemin-pngquant as per example in npm.

events.js:141
      throw er; // Unhandled 'error' event
