Cannot find module @angular/core + angular2

Question

I am trying to create an Angular 2 application using Typescript in Visual Studio 2015. I have installed npm on my machine. When I compile my application , I am getting errors cannot find module '@angular/core'. It is referred in all the ts files under the node_modules folder in the import statement. For e.g.

import { ElementRef, AfterViewInit, OnDestroy, DoCheck, EventEmitter, IterableDiffers } from '@angular/core';

I am currently getting around 500 plus errors. The error goes off when I replace it with 'angular2/core '. Also just to let you know , I am using PrimeNG UI Components in my project as well.

Could somebody help ? I don't understand why it is looking at @angular/core ?

Answer 1

1. Install nodejs
2. Open cmd prompt and type 'cd your project directory'
3. Type 'npm install' and hit enter.

This will create a node_modules folder within that directory which should have the @angular/core that's required.

Answer 2

The angular2 name in modules names is for versions before RC (release candidate) versions (beta ones) and the @angular one for RC versions.
