Angular2 systemjs.config.js ' "ReferenceError: System is not defined"

I have read all the other posts with this identical issue, but haven't been able to resolve the problem.

If I compile to javascript in the browser, I get two 404 errors for @angular/http and @angular/core.

When I set the config file to transpile first, I get a compilation error in system.config.js:

'ReferenceError: System is not defined' at this line

  var setPackageConfig = System.packageWithIndex ? packIndex : packUmd;

I started the project from the quick-start guide and Tour of Heros Http sample.

After comparing all my files against those in the quick-start, I went through and copied the quick start files into my project.

I'm sure I'm missing something basic, but have hit a dead end. FYI: I am new to Angular and Angular2. Using WebStorm to develop and compile.

Here is the index.html and systemjs.config.js

//system.config.js
(function(global) {
    // map tells the System loader where to look for things
    var map = {
        'app':                        'app', // 'dist',
        '@angular':                   'node_modules/@angular',
        'angular2-in-memory-web-api': 'node_modules/angular2-in-memory-web-api',
        'rxjs':                       'node_modules/rxjs'
    };
    // packages tells the System loader how to load when no filename and/or no extension
    var packages = {
        'app':                        { main: 'main.js',  defaultExtension: 'js' },
        'rxjs':                       { defaultExtension: 'js' },
        'angular2-in-memory-web-api': { main: 'index.js', defaultExtension: 'js' },
    };
    var ngPackageNames = [
        'common',
        'compiler',
        'core',
        'forms',
        'http',
        'platform-browser',
        'platform-browser-dynamic',
        'router',
        'router-deprecated',
        'upgrade',
    ];
    // Individual files (~300 requests):
    function packIndex(pkgName) {
        packages['@angular/'+pkgName] = { main: 'index.js', defaultExtension: 'js' };
    }
    // Bundled (~40 requests):
    function packUmd(pkgName) {
        packages['@angular/'+pkgName] = { main: '/bundles/' + pkgName + '.umd.js', defaultExtension: 'js' };
    }
    // Most environments should use UMD; some (Karma) need the individual index files
    var setPackageConfig = System.packageWithIndex ? packIndex : packUmd;
    // Add package entries for angular packages
    ngPackageNames.forEach(setPackageConfig);
    var config = {
        map: map,
        packages: packages
    };
    System.config(config);
})(this);

Edit: This is the point in my http-service.component.ts file where I receive the 404 errors:

import { Injectable } from '@angular2/core';
import { Http, Response } from '@angular2/http';
import { Headers, RequestOptions } from '@angular2/http';
import { Observable } from 'rxjs/Observable';

Please let me know what other files will help. I appreciate any insight!

current versions of angular 2 use '@angular' instead of what beta was using 'angular2'

import { Injectable } from '@angular/core';
import { Http, Response } from '@angular/http';
import { Headers, RequestOptions } from '@angular/http';
import { Observable } from 'rxjs/Observable';
