在github上面找了一個ES5寫的angular2demo(angular2-es5-website-routes)，這個demo在本地是可以運行的，但我升級了angular2相關版本到2.1後，注入angular2自帶的router模組時報錯。
zone.js:158 Uncaught Error: Component class0 is not part of any NgModule or the module has not been imported into your module.
我的程式碼如下：
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 = {}));

類似的npm 升級問題首要考慮的是各個安裝包的依賴問題，你抱錯的檔案是zone.js 就著重對著它的版本號做修改，在package.json 裡把zone.js 的版本號設置為預設的
0.6.12，依然抱錯的話對應的給到0.6.13 或更高，具體的版本去https://github.com/angular/zo... 的tag 裡看，如果最新版本之前都測試過並且出錯，可以考慮看看官方文檔對於2.0 到2.1 的change-log： https://angular.io/docs/ts/la... 最新的句法只能自己研究英文文檔了，想深入研究的話建議看源碼倉庫的修改日誌https://github.com/angular/an...，希望有助於你解決類似問題，最後忠告，不要對你的依賴倉庫進行統一的升級，一但版本號最初寫死了就不要升級了，不然之後的bug 很難清理。專案越大依賴套件越多就越難排查。
