ng serve error: "Cannot read property '0' of undefined" - angularjs

Question

I'm new to Angular. I downloaded the Angular 2 quick-start template from https://github.com/angular/quickstart (app folder is inside an src folder), and then used VS code to modify packages.json content and manually create files/folders inside the app folder for components/services/etc.. based on tutorials that I found online. The application runs and works fine when I kick it off using npm start but I'm stuck creating the DIST folder which I need in order to upload a minified version of my application to azure web app. Whenever I run ng build from the root of my angular 2 project, I get the below error:
Cannot read property '0' of undefined
TypeError: Cannot read property '0' of undefined

Issue was resolved by installing the latest version of Angular CLI (1.0.0-rc.1) and recreating the Angular project (using ng new projectname command) and copying my TS files from my old project over.
