angular material2 does not work in an Angular 2.0.0 app

I have an app that loads with Angular 2.0.0, the 9/14/16 release after all the rc releases. I am trying to add Angular Material2, the official MD release from the Google team. I am copy/pasting code from their Getting Started site, except I am using Atom and not angular-cli, as I have already built the beginnings of the app. Atom-typescript finds everything and says there are no errors. But despite thrashing with a lot of trials, I repeatedly get these not found Console errors when the modified app fails to load.

zone.js:1263 GET http://localhost:3000/node_modules/@angular2-material/button/ 404 (Not Found)scheduleTask @ zone.js:1263

home:27 Error: (SystemJS) XHR error (404 Not Found) loading http://localhost:3000/node_modules/@angular2-material/button(…)

zone.js:1263 GET http://localhost:3000/node_modules/@angular2-material/list/ 404 (Not Found)

I have looked at the node_modules files above and they exist in my code.

Per instructions in Getting Started, relevant code is:


import { MdButtonModule } from '@angular2-material/button';
import { MdListModule } from '@angular2-material/list';
imports: [ BrowserModule,


var map = {
'@angular2-material': 'node_modules/@angular2-material',
'@angular2-material/core': 'node_modules/@angular2-material/core/core',
'@angular2-material/list': 'node_modules/@angular2-material/list',
'@angular2-material/button': 'node_modules/@angular2-material/button'
var packages = {
'app': { main: 'main.js', defaultExtension: 'js' },
'rxjs': { defaultExtension: 'js' },
'angular2-in-memory-web-api': { main: 'index.js', defaultExtension: 'js' },
function packIndex(pkgName) {
packages['@angular/'+pkgName] = { main: 'index.js', defaultExtension: 'js' };
function packUmd(pkgName) {
packages['@angular/'+pkgName] = { main: 'bundles/' + pkgName + '.umd.js', defaultExtension: 'js' };
var setPackageConfig = System.packageWithIndex ? packIndex : packUmd;

The HTML page has a couple md-list, md-list-item and md-button tags.

What should I change?

I was able to get it working this morning as of (9/16) with Angular2 (final), Angular2-Material 2.0.0-alpha.8-2, and TypeScript 2.0.0. As you can see in the package.json below, I have a majority of the currently available Angular2 Material components installed (and running) by following the instructions from this video.

Posting my system.config.ts so you can see it in hopes that it will help you troubleshoot.

 * System configuration for Angular 2 samples
 * Adjust as necessary for your application needs.
(function (global) {

      // paths serve as alias

Updated typescript to version 2.0.0.

Also had to register typings for hammerjs (Touch gesture support), but I believe you'll only need this if you're using MdIconModule.
