如何修复

Answer 1

更新＆gt; = rc.5

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

更新＆gt; = rc.0

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

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

<强>原始

更改

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

到

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

移出的出口的完整清单：

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

位置和HashLocationStrategy在测试版中停止工作
