Angular CLI 中未显示字体精美的图标：8.2.2 而是显示正方形

我已经安装了 Font Awesome 通过npm install --save font-awesome angular-font-awesome from https://www.npmjs.com/package/angular-font-awesome https://www.npmjs.com/package/angular-font-awesome.

将其链接到 angular.json 中

"styles": [
     "src/styles.css",
     "node_modules/font-awesome/css/font-awesome.min.css"
]

在index.html中我已经链接了库

<link rel="stylesheet" type="text/css" href="../node_modules/font-awesome/css/font-awesome.min.css">

我的图标 html 代码如下所示：

<i class="fa fa-facebook-f"></i>

并且仍然显示方块而不是图标。

有人可以帮忙吗？

要安装“font-awesome”，请使用：

$ npm install @fortawesome/angular-fontawesome@<version>
$ npm install @fortawesome/fontawesome-svg-core
$ npm install @fortawesome/free-solid-svg-icons

然后我们需要将其导入app.module.ts:

imports: [
    BrowserModule,
    FontAwesomeModule
],

src/app/app.component.html：

<div style="text-align:center">
  <fa-icon [icon]="faCoffee"></fa-icon>
</div>

src/app/app.component.ts

import { Component } from '@angular/core';
import { faCoffee } from '@fortawesome/free-solid-svg-icons';

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

UPDATE:

可以通过添加来使用 Facebook fontawesomefaFacebook图标。让我举个例子。

安装包free-regular-svg-icons:

npm i --save @fortawesome/free-regular-svg-icons

安装包free-regular-svg-icons:

npm i --save @fortawesome/free-brands-svg-icon

应用程序模块.ts：

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

import { FontAwesomeModule, FaIconLibrary } from '@fortawesome/angular-fontawesome';
import { faSquare, faCheckSquare } from '@fortawesome/free-solid-svg-icons';
import { faSquare as farSquare, faCheckSquare as farCheckSquare } from '@fortawesome/free-regular-svg-icons';
import { faStackOverflow, faGithub, faMedium, faFacebook } from '@fortawesome/free-brands-svg-icons';

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

@NgModule({
  imports:      [ BrowserModule, FormsModule, FontAwesomeModule ],
  declarations: [ AppComponent, HelloComponent ],
  bootstrap:    [ AppComponent ]
})
export class AppModule {
  constructor(private library: FaIconLibrary) {
    library.addIcons(faSquare, faCheckSquare, farSquare
        , farCheckSquare, faStackOverflow, faGithub, faMedium, faFacebook);
  }
}

应用程序组件.html：

<div style="text-align:center">
  <h2>Using Brand Icons</h2>
  <fa-icon [icon]="['fab', 'stack-overflow']"></fa-icon>
  <br>
  <fa-icon [icon]="['fab', 'github']"></fa-icon>
  <br>
  <fa-icon [icon]="['fab', 'medium']"></fa-icon>
  <br>
  <fa-icon [icon]="['fab', 'facebook']"></fa-icon>  
  <br>
</div>
