Running gulp command results in error

[invot]

The idea behind pho is incredible. However, despite multiple attempts, I can't get anything to run. Following your Getting Started guide, while running the gulp command I get the following error:

C:\code\pho>gulp
C:\code\pho\node_modules\socket.io\lib\store.js:35
Store.prototype.__proto__ = EventEmitter.prototype;
                                         ^

TypeError: Cannot read property 'prototype' of undefined

This is a fresh install, and node/npm is up-to-date.
