Question

当我将angular2测试应用程序从beta-14转换为rc1时。我收到以下错误

ZoneDelegate.invoke @ angular2-polyfills.js:349 Error: Cannot read property 'toString' of undefined(…)

发出此错误的代码在这里

    346 ZoneDelegate.prototype.invoke = function (targetZone, callback, applyThis, applyArgs, source) {
    347     return this._invokeZS
    348         ? this._invokeZS.onInvoke(this._invokeDlgt, this.zone, targetZone, callback, applyThis, applyArgs, source)
    349         : callback.apply(applyThis, applyArgs);
    350 };

导致错误的代码是main.ts

import {bootstrap}    from '@angular/platform-browser-dynamic';
import {provide, ComponentRef} from '@angular/core';
import {ROUTER_PROVIDERS } from '@angular/router-deprecated';
// ,LocationStrategy, HashLocationStrategy
import { HTTP_PROVIDERS }    from '@angular/http';
import 'rxjs/Rx';
import {APP_BASE_HREF} from '@angular/common'

import {AppComponent} from './appShell/app.component';
import {appInjector} from './login/auth.injector';
import {Authentication} from './login/auth.service';

bootstrap(AppComponent, [
  ROUTER_PROVIDERS,
  //provide(LocationStrategy, {useClass: HashLocationStrategy}),
  provide(APP_BASE_HREF, {useValue: location.pathname}),
  Authentication,
  HTTP_PROVIDERS
])//.catch(err => console.error(err));
.then((appRef: ComponentRef<any>) => {
  // store a reference to the application injector
  appInjector(appRef.injector);
});

我使用了router-deprecated以实现向后兼容。此代码曾用于beta-14。

我使用了来自https://plnkr.co/edit/yRKhoOelf2uJ3yAsdIMm?p=preview的config.js。

LocationStrategy，HashLocationStrategy已被注释掉，因为它已不再包含在路由器中。是否被

取代

provide(APP_BASE_HREF, {useValue: location.pathname})  ?

更重要的是，我能做些什么才能让它发挥作用？

看起来config.js是错误的。

我在the doc找到了官方插件，并没有显示任何错误。

如上所述，您可以在LocationStrategy中找到HashLocationStrategy和@angular/common。
