You need npm 3.x.x or higher. Upgrade npm version and then try again. — Sanket, Sep 06 '16 at 17:13
i upgraded to npm but still having the same problem. http://prntscr.com/cewf5y — Uğur Demir, Sep 06 '16 at 17:54
are you working out of VS? if so it may not be picking up your updates to npm and still referencing the old versions — Bean0341, Sep 06 '16 at 18:50
Also if your positive your project is referencing the correct versions of npm and node, then you will need to provide more info on your project. I.E your package.json and your systemjs.config.js, these are important to diagnosing this type of issue. — Bean0341, Sep 06 '16 at 19:02

Please check if the start field in package.json is

"start": "concurrently \"npm run tsc:w\" \"npm run lite\" "

and not

"start": "tsc && concurrently \"npm run tsc:w\" \"npm run lite\" "

Install the latest versions of node and angular/cli,you can check the version of node using node -v,npm version using npm -v and angular/cli version using angular --version or ng -version and in package.json file change to either start": "ng serve --host 0.0.0.0 or start": "lite-server.It's better if you install angular/cli globally.
