Building an Angular 2 App with Clarity Design System

I'm getting this error after adding Clarity Design System from their official tutorial to angular 2 5min quickstart . The error in browser's console doesn't help too much, any advice please?

zone.js:1382 GET http://localhost:3000/clarity-angular 404 (Not Found)
Error: (SystemJS) XHR error (404 Not Found) loading http://localhost:3000/clarity-angular(…)


app.module.ts

import {NgModule} from '@angular/core';
import {BrowserModule} from '@angular/platform-browser';
import {ClarityModule} from 'clarity-angular';
import {AppComponent} from './app.component';

@NgModule({
imports: [BrowserModule,
ClarityModule],
declarations: [AppComponent],
bootstrap: [AppComponent]
})
export class AppModule {
}

UPDATED Add clarity-angular to map and package sections. See example below.

(function (global) {
  System.config({
    paths: {
      // paths serve as alias
      'npm:': 'node_modules/',
      'build:': 'build',
      'src:': ''
    },
    // map tells the System loader where to look for things
    map: {
      // our app is within the app folder
      //app: 'build:',
      app: 'app',
      // angular bundles
      '@angular/core': 'npm:@angular/core/bundles/core.umd.js',
      '@angular/common': 'npm:@angular/common/bundles/common.umd.js',
      '@angular/compiler': 'npm:@angular/compiler/bundles/compiler.umd.js',
      '@angular/platform-browser': 'npm:@angular/platform-browser/bundles/platform-browser.umd.js',
      '@angular/platform-browser-dynamic': 'npm:@angular/platform-browser-dynamic/bundles/platform-browser-dynamic.umd.js',
      '@angular/http': 'npm:@angular/http/bundles/http.umd.js',
      '@angular/router': 'npm:@angular/router/bundles/router.umd.js',
      '@angular/forms': 'npm:@angular/forms/bundles/forms.umd.js',
      '@angular/upgrade': 'npm:@angular/upgrade/bundles/upgrade.umd.js',
      // other libraries
      'rxjs': 'npm:rxjs',
      'angular-in-memory-web-api': 'npm:angular-in-memory-web-api/bundles/in-memory-web-api.umd.js',
      //'angular2-mdl': 'npm:angular2-mdl/bundle/angular2-mdl.js'
      //'angular2-mdl': 'npm:angular2-mdl',
      'clarity-angular': 'npm:clarity-angular'
    },
    // packages tells the System loader how to load when no filename and/or no extension
    packages: {
      app: {
        main: 'main.js',
        defaultExtension: 'js'
      },
      rxjs: {
        main: 'Rx.js',
        defaultExtension: 'js'
      },
      'clarity-angular': {
        main: 'index.js',
        defaultExtension: 'js'
      }
    }
  });
})(this);

If you are using Clarity directives directly in your main app.component.html you need to import { ClarityModule } from 'clarity-angular'; and also add ClarityModule to @NgModule imports. If you need to use Clarity directives under a Router you should also import ClarityModule in you application router module

import { NgModule }             from '@angular/core';
import { RouterModule, Routes } from '@angular/router';
import { FormsModule, ReactiveFormsModule } from '@angular/forms';

import { ClarityModule } from 'clarity-angular';

import { SearchFormComponent } from './components/search-form/search-form.component';

const routes: Routes = [
     { path: 'search', component: SearchFormComponent }
];
@NgModule({
    imports: [
        FormsModule,
        ReactiveFormsModule,
        ClarityModule,
        RouterModule.forRoot(routes)
    ],
    declarations: [
        SearchFormComponent
    ],
    exports: [ RouterModule ]
})
export class AppRoutingModule {}
