Angular 6中的FontAwesome图标? [英] FontAwesome Icons in Angular 6?

问题描述

我正在尝试在Angular项目中使用FontAwesome中的图标.
我从入门"指南开始，您可以在这里找到: FontAwesome Angular入门

I'm trying to use icons from FontAwesome in an Angular project.
I started with the "Getting Started" guide you can find here: FontAwesome Angular Getting Started

一切正常，无论我将其放在模板中的什么位置，我都可以看到faCoffee图标.但是，如果我尝试将其更改为另一个图标(例如检查"图标)，则不会显示任何内容.

Everything works fine, i can see the faCoffee icon wherever i put it in my templates. But if I try to change it to another icon (ex. the "check" icon), nothing is shown.

我在组件级别更改了图标声明，使其看起来像这样:

I changed my icon declaration at component-level to make it look like this:

import { faCheck } from '@fortawesome/free-solid-svg-icons';

更改了html模板以显示我的新图标:

Changed the html template to show my new icon:

<fa-icon [icon]="faCheck"></fa-icon>

然后在我的组件中分配图标字段:

Then the icon field assignment in my component:

faCheck = faCheck;

请注意，在我上面测试的示例中，我实际上仅更改了图标的名称，这些示例在上面发布的网址中起作用.即使我在声明中使用"faCheck"的定义，我也会看到它已定义，因此我希望它可以使用.

Please note that i'm changing essentially only the name of the icon from the examples that i tested and are working at the Url i posted above. Even if I go to the definition of "faCheck" on my declaration, i see that it's defined so I expect it to be available.

Chrome控制台在页面加载时显示此错误:

Chrome console shows this error when page is loading:

FontAwesome:找不到图标.似乎您已为此组件提供了一个空或未定义的图标对象.

FontAwesome: Could not find icon. It looks like you've provided a null or undefined icon object to this component.

首次尝试在我的项目中使用FontAwesome，欢迎提供有用的常规信息.

First attempt to use FontAwesome in my projects, useful general informations are welcome.

更新:它可以正常重建我的整个应用程序.我使用的是VS Code，因此当您保存文件时，他尝试重新创建最终的包以使您能够浏览和检查开发情况.我不知道组件在内存中的状态到底会发生什么.我认为该图标未显示，因为引用存在一些偏差.

UPDATE: Got it working rebuilding my entire application. I was using VS Code, so when you save a file he tries to recreate the final bundle to let you navigate and check your development. I don't know what really happens with components in-memory state. I think the icon was not showing because of some misalignment of references.

推荐答案

您要做的就是:

1-将此添加到您的index.html:

1 - add this to your index.html:

<link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.2.0/css/all.css" integrity="sha384-hWVjflwFxL6sNzntih27bfxkr27PmbbK/iSvJ+a4+0owXq79v+lsFkW54bOGbiDQ" crossorigin="anonymous">

2-将您的图标用作:

2 - use your icon as:

<i class="fas fa-check"></i>

您不必在component.ts或app.module.ts中添加任何内容，也无需使用yarn或npm安装任何内容.

You don't have to add anything in your component.ts nor in your app.module.ts nor install anything with yarn or npm.

为了回答您的问题，这是本教程中提到的使用faCheck进行的堆栈闪电测试，它对我有用: https ://stackblitz.com/edit/angular-4ebr9t

To answer you question, here is a stackblitz with the faCheck used as mentioned in the tutorial, it's working for me: https://stackblitz.com/edit/angular-4ebr9t

检查是否按照教程中的说明安装了所有依赖项.

check if you installed all the dependencies as said in the tutorial.
