Unable to resolve dependencies like “@angular/common”

Hi,
first you must update your config.yaml
section:

packages:
  '@*/*':
    # scoped packages
    access: $all
    publish: $authenticated
    proxy: npmjs

in default config.yaml there is no proxy setting.

If anyone has this problem, workaround for this is:
Option 1: in sinopia/lib/up-storage.js
change code on line number 10

var encode         = function(thing) {
  return encodeURIComponent(thing).replace(/^%40/, '@');
};

Option 2: set npm scoped registry to npmjs.org
npm config set "@angular:registry" http://registry.npmjs.org/

taobao npm:   https://registry.npm.taobao.org
