Question

我只是想在 Angular2 中运行一个简单的index.html页面，但它在控制台的zone.js中显示错误：

    Unhandled Promise rejection: No ErrorHandler. Is platform module (BrowserModule) included? ; Zone: <root> ; Task: Promise.then ; Value: Error: No ErrorHandler. Is platform module (BrowserModule) included?
    at eval (application_ref.ts:364)
    at ZoneDelegate.invoke (zone.js:391)
    at Object.onInvoke (ng_zone.ts:296)

有人可以帮助我基本上是什么以及如何解决这个问题。模块文件：

import {Component, NgModule} from "@angular/core";
import {App} from "./app";

@NgModule({
    declarations: [App],
    bootstrap: [App]
})
export class AppModule {

}

Answer 1

你错过了

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

添加到您的应用模块

@NgModule({
imports: [
    BrowserModule,
]
...})

Angular2错误 - 是否包含平台模块（BrowserModule）？
