what does node version and npm version say? – longbow
node version : v4.5.0 npm version : 2.15.9 – Uğur Demir
You need npm 3.x.x or higher. Upgrade npm version and then try again. – Sanket
i upgraded to npm but still having the same problem. prntscr.com/cewf5y – Uğur Demir
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

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.
