title: Package is not working angular 2
body: <p>I am new to angular2 and I have problem with angular 2 package. I have been trying to fix the problem and I couldn't. I am doing some assignment/project and the teacher provide with <code>package.json</code> with assignment. I install npm in locally on project folder as well as globally, but I couldn't start local server. I am running the program at window. The problem is here, when I run npm start or npm start -server I got the following error:</p>
  
  <pre><code>npm ERR! node v6.9.2
  npm ERR! npm  v2.12.1
  npm ERR! code ELIFECYCLE
  npm ERR! angular2-boilerplate@1.0.0 start: `gulp`
  npm ERR! Exit status 1
  npm ERR!
  npm ERR! Failed at the angular2-boilerplate@1.0.0 start script 'gulp'.
  npm ERR! This is most likely a problem with the angular2-boilerplate package,
  npm ERR! not with npm itself.
  npm ERR! Tell the author that this fails on your system:
  npm ERR!     gulp
  npm ERR! You can get their info via:
  npm ERR!     npm owner ls angular2-boilerplate
  npm ERR! There is likely additional logging output above.
