Ng build——prod删除导航条

Question

由于某种原因，--prod cli标志从编译的输出中删除了导航栏。知道为什么吗?

我的app.component是这样的:

import { Component } from '@angular/core';
import { ROUTER_DIRECTIVES } from '@angular/router';
@Component({
  selector: 'app-root',
  template: `
            <nav-bar></nav-bar>
             <router-outlet>
            </router-outlet>`,
  directives: [ROUTER_DIRECTIVES]
})
export class AppComponent {}

我的导航栏组件:

import { Component, OnInit } from '@angular/core';
import { GlobalEvent } from '../shared/global.event'
import { Http, Response } from '@angular/http';
@Component({
    selector: 'nav-bar',
    templateUrl: 'navbar.component.html',
    providers: [GlobalEvent],
    styleUrls: ['navbar.component.css'],
})
export class NavbarComponent implements OnInit {
   ...
}

注:具有--dev标志的建筑按预期工作。我希望这不是cli的问题

显然这是angular-cli的一个已知问题。看到这里。

Fix is going to nano node_modules/angular-cli/addon/ng2/models/webpack-build-production.ts

和变化的mangle: { screw_ie8 : true }, //prod

到mangle: { screw_ie8 : true, keep_fnames:true }, //prod
