我正在使用 Angular 6 angular-starter 和 fontawesome，然后是 这里 关于如何将 fa 安装到 ng.

在我的 .ts 中是这样的:

import { library, dom } from '@fortawesome/fontawesome-svg-core';从'@fortawesome/free-brands-svg-icons/faInstagram'导入{faInstagram}；从@fortawesome/free-solid-svg-icons/faLink"导入{faLink}；公共 ngOnInit() {library.add(faInstagram);library.add(faLink);dom.watch();}

然后在 .html 中:

<fa-icon [icon]="['fab', 'instagram']"></fa-icon>

除了免费品牌，@fortawesome/free-brands-svg-icons 之外，它工作得很好.在构建 (npm start) 时，它会产生错误/警告 IconDefinition"类型的参数不可分配给IconDefinitionOrPack"类型的参数.IconDefinition"不可分配给IconPack"类型.'IconDefinition' 类型中缺少签名. 在 92% 的构建中，但实际上构建似乎成功并且显示了 instagram 图标，但我很烦恼，因为代码下方出现了一条红线.

有人能弄清楚吗?

我的 package.json

"@fortawesome/angular-fontawesome": "^0.3.0","@fortawesome/fontawesome-svg-core": "^1.2.6","@fortawesome/free-brands-svg-icons": "^5.4.2","@fortawesome/free-solid-svg-icons": "^5.4.1",

解决方案

我将提到一个带有常规图标的案例.希望类似的方法对您有所帮助.您只需导入图标，然后将其从 IconDefinitionOrPack 类型转换为 IconDefinition，同时将其添加到模块构造函数中的库中.

import { faTimesCircle, faCheckCircle } from '@fortawesome/free-regular-svg-icons';

然后在将它添加到库中时对其进行类型转换

 导出类 AppModule {构造函数(){library.add(faTable);library.add(faChartArea);library.add(faTachometerAlt);library.add(faTimesCircle as IconDefinition);library.add(faCheckCircle as IconDefinition);}}

在 HTML 中，

<fa-icon [icon]="['far', 'check-circle']"></fa-icon><span>税务信息</span>

I'm using Angular 6 angular-starter and fontawesome, followed here on how to install fa to ng.

In my .ts looks like this:

import { library, dom } from '@fortawesome/fontawesome-svg-core';
import { faInstagram } from '@fortawesome/free-brands-svg-icons/faInstagram';
import { faLink } from '@fortawesome/free-solid-svg-icons/faLink';

public ngOnInit() {
    library.add(faInstagram);
    library.add(faLink);
    dom.watch();
}

Then in .html:

<fa-icon [icon]="['fab', 'instagram']"></fa-icon>

It works perfectly fine except for free brands, @fortawesome/free-brands-svg-icons. On build (npm start) it produces error/warning Argument of type 'IconDefinition' is not assignable to parameter of type 'IconDefinitionOrPack'. 'IconDefinition' is not assignable to type 'IconPack'. signature is missing in type 'IconDefinition'. on the 92% build but actually the build appears to be successful and the instagram icon shows up but I'm bothered because a red line below the code appears.

Can someone figure it out?

My package.json

"@fortawesome/angular-fontawesome": "^0.3.0",
"@fortawesome/fontawesome-svg-core": "^1.2.6",
"@fortawesome/free-brands-svg-icons": "^5.4.2",
"@fortawesome/free-solid-svg-icons": "^5.4.1",

解决方案

I'll mention a case with regular icons. Hope a similar approach will help you. You can just import the icon and then typecast it from IconDefinitionOrPack to IconDefinition while adding it to the library in your module constructor.

import { faTimesCircle, faCheckCircle } from '@fortawesome/free-regular-svg-icons';

Then while adding it in library typecast it

  export class AppModule {
    constructor() {
      library.add(faTable);
      library.add(faChartArea);
      library.add(faTachometerAlt);
      library.add(faTimesCircle as IconDefinition);
      library.add(faCheckCircle as IconDefinition);
    }
  }

In HTML,

<div class="col-md-6">
   <fa-icon [icon]="['far', 'check-circle']"></fa-icon>
   <span>Tax Info</span>
</div>
