我最近从RC4升级到RC5,并没有更改任何代码,但应用程序已损坏.这是错误消息：
<html>
<head>
<script>
var pjson = require('./package.json');
document.title = pjson.name;
</script>

更新：现在使用Angular-CLI,不再有任何问题.
看起来你必须将ElementRef拉入@NgModule注释的导入部分,例如我在
my app的这个例子中所做的.
如果这对你没有任何意义,那么你需要阅读RC.5对Angular 2所做的重大修改.他们是蠢货.这是documentation for NgModule.你会发现它在Quickstart Docs中使用的一个非常基本的例子.如果我的个人经验有任何迹象,你的应用程序需要进行大修才能使其正常运行.几个小时后我还没有让我的工作再次开始,我的是一个非常基本的应用程序.
// app.module.ts
// Angular 2 imports
import { NgModule,ElementRef } from '@angular/core'; // <--- Import ElementRef
import { BrowserModule } from '@angular/platform-browser';
import { RouterModule } from '@angular/router'
import { HTTP_PROVIDERS } from '@angular/http';
import { COMMON_DIRECTIVES } from '@angular/common';
// My components and services (yours will certainly differ)
import {PublicPage} from './components/pages/public-page'
import {ProtectedPage} from './components/pages/protected-page'
import {LoggedoutPage} from "./components/pages/loggedout-page";
import { APP_ROUTES } from './app.routes';
import { WindowService } from './services/window.service';
import { AuthService } from './services/auth.service';
import { CookieService } from './services/cookies.service';
// My main component for this app/module
import { AppComponent } from './app.component';
@NgModule({
// Add ElementRef to the module imports below
imports: [ ElementRef,BrowserModule,RouterModule.forRoot(APP_ROUTES) ],declarations: [ AppComponent,PublicPage,ProtectedPage,LoggedoutPage ],bootstrap: [ AppComponent ],providers: [ WindowService,AuthService,CookieService,HTTP_PROVIDERS,COMMON_DIRECTIVES ]
})
export class AppModule { }
然后我用这样的东西来升级模块：
// main.ts
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app.module';
platformBrowserDynamic().bootstrapModule(AppModule);
