Updating to Angular2.0.0-rc.1, can't get past this error
<p>App refuses to find <code>symbol-observable</code> - or zone.js does - even though rxjs is definitely in there.</p>

<p>Got everything loading like:</p>

<pre><code>&lt;script src="node_modules/es6-shim/es6-shim.js"&gt;&lt;/script&gt;
&lt;script src="node_modules/zone.js/dist/zone.js"&gt;&lt;/script&gt;
&lt;script src="node_modules/reflect-metadata/Reflect.js"&gt;&lt;/script&gt;
&lt;script src="node_modules/systemjs/dist/system.src.js"&gt;&lt;/script&gt;
&lt;script&gt;
System.config({
  map: {
    '@angular': 'node_modules/@angular',
    'rxjs': 'node_modules/rxjs'
  },
  packages: {
    'dist': { defaultExtension: 'js', format: 'register', main: 'boot.js' },
    '@angular/common': { defaultExtension: 'js', main: 'index.js' },
    '@angular/compiler': { defaultExtension: 'js', main: 'index.js' },
    '@angular/core': { defaultExtension: 'js', main: 'index.js' },
    '@angular/http': { defaultExtension: 'js', main: 'index.js' },
    '@angular/platform-browser': { defaultExtension: 'js', main: 'index.js' },
    '@angular/platform-browser-dynamic': { defaultExtension: 'js', main: 'index.js' },
    '@angular/router': { defaultExtension: 'js', main: 'index.js' },
    'rxjs': { defaultExtension: 'js' }
  }
});
System.import('dist').catch(console.error.bind(console));
&lt;/script&gt;
</code></pre>

<p>I put all the code up <a href="https://github.com/RyanMetin/slush-angular2/tree/rc1" rel="noreferrer">here</a> for a closer look.</p>
