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 = {}));

For similar npm upgrade issues, the first consideration is the dependency of each installation package. The file you are wrong about is zone.js, so focus on modifying its version number. Set the version number of zone.js in package.json. It is the default 0.6.12. If you still get the error, the corresponding version will be 0.6.13 or higher. For the specific version, go to the tag of https://github.com/angular/zo... to see if the latest version has been tested before. and an error occurs, you can consider taking a look at the official documentation for the change-log from 2.0 to 2.1: https://angular.io/docs/ts/la... For the latest syntax, you can only study the English documentation yourself. If you want to study in depth It is recommended to read the modification log of the source code repository https://github.com/angular/an..., I hope it will help you solve similar problems. Finally, a word of advice, do not perform a unified upgrade of your dependent repositories. Once the version number is the first Don't upgrade if it's hardcoded, otherwise it will be difficult to clean up future bugs. The larger the project and the more dependent packages it has, the more difficult it will be to troubleshoot.
