如何解决

Answer 1

更新 >= rc.5

@NgModule({
  providers: [{ provide: LocationStrategy, useClass: HashLocationStrategy}]
})
export class AppModule {}

更新 >= rc.0

import {  
  PlatformLocation,  
  Location,  
  LocationStrategy,  
  HashLocationStrategy,  
  PathLocationStrategy,  
  APP_BASE_HREF}  
from '@angular/common';  

import {BrowserPlatformLocation} from   '@angular/platform-browser';

原创

改变

import {ROUTER_PROVIDERS, LocationStrategy, HashLocationStrategy} from 'angular2/router';

到

import {ROUTER_PROVIDERS} from 'angular2/router';
import {LocationStrategy, HashLocationStrategy} from 'angular2/platform/common';

import {  
  PlatformLocation,  
  Location,  
  LocationStrategy,  
  HashLocationStrategy,  
  PathLocationStrategy,  
  APP_BASE_HREF}  
from 'angular2/platform/common';  

import {BrowserPlatformLocation} from   'angular2/src/platform/browser/location/browser_platform_location';

此更改通常导致的另一个错误是

location.createComponent 不是函数
