angular - Error loading http://localhost:4200/app/subjects.component.js as "./subjects.component" from http://localhost:4200/app/app.routes.js -


what possible meaning of these errors? uncaught referenceerror: require not defined

get http://localhost:4200/traceur 404 (not found)

potentially unhandled rejection [5] error: xhr error (404 not found) loading http://localhost:4200/traceur @ xmlhttprequest.wrapfn [as _onreadystatechange] (http://localhost:4200/vendor/zone.js/dist/zone.js:769:30) @ zonedelegate.invoketask (http://localhost:4200/vendor/zone.js/dist/zone.js:356:38) @ zone.runtask (http://localhost:4200/vendor/zone.js/dist/zone.js:256:48) @ xmlhttprequest.zonetask.invoke (http://localhost:4200/vendor/zone.js/dist/zone.js:423:34) error loading http://localhost:4200/traceur error loading http://localhost:4200/app/subjects.component.js "./subjects.component" http://localhost:4200/app/app.routes.js

app.routes.ts:

import { providerouter, routerconfig } '@angular/router'; import {subjectscomponent} './subjects.component'; import {basiccardcomponent} './basiccard.component';   export const routes: routerconfig = [   { path: '', component: subjectscomponent },  ];  export const approuterproviders = [   providerouter(routes) ];

subjects.component.ts:

import {component} '@angular/core'; import {bootstrap} '@angular/platform-browser-dynamic'; import {mdbutton} '@angular2-material/button'; import {mdcard} '@angular2-material/card'; import {mdtoolbar} '@angular2-material/toolbar'; import {mdicon,mdiconregistry} '@angular2-material/icon'; import {mdtab} '@angular2-material/tabs'; import {mdinput,md_input_directives} '@angular2-material/input'; import {mdcheckbox} '@angular2-material/checkbox';  import { router_directives} '@angular/router'; import { providerouter, routerconfig } '@angular/router';  import {profiledetailscomponent} './profiledetails.component'; //import {agreementcomponent} './agreement.component';  @component({     selector: 'subjects',     templateurl: 'app/subjects.component.html' ,     styleurls: ['app/app.component.css'],     directives: [//agreementcomponent,      mdbutton,mdcard,mdtoolbar,mdicon,mdinput,md_input_directives,mdcheckbox,profiledetailscomponent,router_directives],      providers:[mdiconregistry] })  export class subjectscomponent{    private buttonstate: boolean = true;    private classes1 = [{label: 'english', state: false},{label:  'hindi', state: false},{label:  'mathematics', state: false},{label:  'science', state: false},{label:  'computer science', state: false},{label:  'social science', state: false},{label:  'environmental studies', state: false}];     setbuttonstate() {     let counter = 0;     for(let i=0;i<this.classes1.length;i++) {           if (this.classes1[i].state === true) {              counter++;           }}        if (counter >= 1) { this.buttonstate = false; }       else {this.buttonstate = true;}   }  }

bearing in mind when question asked, i'm not sure advice you. nevertheless, else receiving (and did using angular cli, while upgrading rc.5 rc.6) make following update system-config.ts:

const packages: = { 'rxjs' : {main: 'rx'}, '@angular/core' : {main: 'bundles/core.umd.min.js', format: 'cjs'}, '@angular/common' : {main: 'bundles/common.umd.min.js', format: 'cjs'}, '@angular/compiler' : {main: 'bundles/compiler.umd.min.js', format: 'cjs'}, '@angular/forms' : {main: 'bundles/forms.umd.min.js', format: 'cjs'}, '@angular/router' : {main: 'bundles/router.umd.min.js', format: 'cjs'}, '@angular/platform-browser' : {main: 'bundles/platform-browser.umd.min.js', format: 'cjs'}, '@angular/platform-browser-dynamic': {main: 'bundles/platform-browser-dynamic.umd.min.js', format: 'cjs'}, '@angular/http' : {main: 'bundles/http.umd.min.js'}, };
