在github上面找了一个ES5写的angular2demo(angular2-es5-website-routes),这个demo在本地是可以运行的,但我升级了angular2相关版本到2.1后,注入angular2自带的router模块时报错。
zone.js:158 Uncaught Error: Component class0 is not part of any NgModule or the module has not been imported into your module.
我的代码如下:
boot.js
(function(app) {
document.addEventListener('DOMContentLoaded', function() {
// ng.platformBrowserDynamic.bootstrap(app.AppComponent, [ng.router.ROUTER_PROVIDERS]);
ng.platformBrowserDynamic
.platformBrowserDynamic()
.bootstrapModule(app.AppModule);
});
})(window.app || (window.app = {}));
app.component.js
(function(app) {
app.AppComponent =
ng.core.Component({
selector: 'app',
templateUrl: 'app/app.component.html',
styleUrls: ['app/app.component.css'],
// directives: [ ng.router.ROUTER_DIRECTIVES ],
providers: [ app.StateService, app.ExperimentsService ]
})
.Class({
constructor: function() {}
});
app.routing = [
{path: '/', component: app.HomeComponent},
{path: '/home', component: app.HomeComponent},
{path: '/about', component: app.AboutComponent},
{path: '/experiments', component: app.ExperimentsComponent},
{path: '/*', component: app.HomeComponent }
];
app.AppModule =
ng.core.NgModule({
imports: [ ng.platformBrowser.BrowserModule, ng.router.RouterModule.forRoot(app.routing) ],
declarations: [ app.AppComponent ],
bootstrap: [ app.AppComponent ]
})
.Class({
constructor: function() {}
});
})(window.app || (window.app = {}));

비슷한 npm 업그레이드 문제의 경우 가장 먼저 고려해야 할 사항은 각 설치 패키지의 종속성입니다. 잘못된 파일은 zone.js이므로 해당 버전 번호를 수정하는 데 집중하세요. package.json. 기본값입니다 0.6.12
. 그래도 오류가 발생하면 해당 버전은 0.6.13 이상입니다. 특정 버전은 https://github.com/angular/zo... 태그로 이동하여 확인하세요. 이전에 최신 버전을 테스트했는데 오류가 발생했다면 2.0에서 2.1로의 변경 로그에 대한 공식 문서(https://angular.io/docs/ts/la...)를 살펴보세요. 최신 구문은 영어 문서만 직접 공부하시면 됩니다. 심도 깊게 공부하고 싶다면 소스코드 저장소 https://github.com/angular/an... 의 수정 로그를 읽어보시는 걸 추천합니다. 유사한 문제를 해결하는 데 도움이 되기를 바랍니다. 마지막으로, 종속 저장소의 통합 업그레이드를 수행하지 마십시오. 일단 버전 번호가 하드 코딩되어 있으면 업그레이드하지 마십시오. 향후 버그를 정리하세요. 프로젝트 규모가 크고 종속 패키지가 많을수록 문제 해결이 더 어려워집니다.
