Angular CLI - angular 5.2.0 with ng-bootstrap 不工作

Question

我正在尝试使用 angular cli and there is a new ng-boostrap module 专门针对 angular 应用程序

设置 angular 应用程序

ng new angular-cli-bootstrap-test
cd angular-cli-bootstrap-test

npm install --save @ng-bootstrap/ng-bootstrap
ng serve

并为 ng-boostrap 添加了一些配置，app.module.ts:

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

import { NgbModule } from '@ng-bootstrap/ng-bootstrap';
import { FormsModule } from '@angular/forms';

import { AppComponent } from './app.component';


@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    FormsModule,
    NgbModule.forRoot()
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

app.component.ts:

import { Component } from '@angular/core';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'app';
  model = {
    left: true,
    middle: false,
    right: false
  };
}

app.component.html:

<div class="btn-group btn-group-toggle">
  <label class="btn-primary" ngbButtonLabel>
    <input type="checkbox" ngbButton [(ngModel)]="model.left"> Left (pre-checked)
  </label>
  <label class="btn-primary" ngbButtonLabel>
    <input type="checkbox" ngbButton [(ngModel)]="model.middle"> Middle
  </label>
  <label class="btn-primary" ngbButtonLabel>
    <input type="checkbox" ngbButton [(ngModel)]="model.right"> Right
  </label>
</div>
<hr>
<pre>{{model | json}}</pre>

抱歉，如果我遗漏了什么，所有内容都显示无误，但没有 bootstrap 样式，也许我遗漏了什么？

页面源形式浏览器：

<!doctype html>
<html lang="en">

  <meta charset="utf-8">

Answer 1

添加css解决了我的问题，ng-boostrap manual

中没有定义

<!doctype html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <title>AngularCliBootstrapTest</title>
  <base href="/">

  <meta name="viewport" content="width=device-width, initial-scale=1">
