Ionic 2 Starter

Hello,

I tried to install ionic 2 alpha tutorial project however the css files are missing in the console it gives me this error message
http://localhost:8100/build/css/app.css Failed to load resource: the server responded with a status of 404 (Not Found)

Also I see the same page when i deploy to android

I followed the guidlines and the commands that i use is the followings:
npm install -g ionic@alpha
ionic start myproject tutorial --v2
cd myproject
ionic serve

for android i use
ionic platform add android
ionic run android

While deploying to android device i do not get any errors. It runs on the device what with pure html, no css, no ionic. I use windows 10 operating system to build.

I really want to try ionic 2 so waiting for your help.
