I can' build the app when following Ember.js 2.4 "Getting Started" guide

I'm trying to learn Ember.js and so I started to read some installation guides with npm. Then I went to try a small Getting Started tutorial guide they have on their website. I followed each step without to much exploration just to see if it worked well.

Everything went fine, the app was loading and acting as expected on localhost:4200 server and it was pretty nice to develop actually. The problem was on the final step, where you have to build the app with your command line using ember build --env production and the dist/ folder will have your final code. The command line trown some errors and when I went to the index.html file on dist/ folder, the page was blank in Chrome.

This happened in MacOS and Windows 10 to. I'm using ember-cli version 2.4.3, node version 4.4.3 and npm version 3.8.9 on a Windows 10 machine x64 architecture.

The error trown by the command line was:

Cleanup error.

I don't know if this affects in anything but I've runned the ember build command while the ember server was still rilling.

I wanted to understand if I'm doing something wrong, or if this ember tutorial is outdated, of if anyone has experienced this same problem and how to solve this issue.

Thanks
