经过一些研究，包括阅读Font Awesome 5 with Angular、文档等，我无法推进 Angular 5 App 和 Font-Awesome 5 (Pro) 之间的集成。
问题：图标不出现。

在我的研究中，我了解到我需要指定我需要使用什么（图标），如下所示：
import {faChevronLeft, faChevronRight} from '@fortawesome/fontawesome-free-solid';
import fontawesome from '@fortawesome/fontawesome';
然后我需要将这些图标传递给 fontawesome 对象：
fontawesome.library.add(faChevronLeft, faChevronRight);
最后我发现（在font-awesome 文档中，我需要调用负责使魔术发生的 i2svg 方法：
fontawesome.dom.i2svg();
文档说我必须调用不带参数的方法。但是编译器将我指向另一个方向，我必须告知以下数据：
export interface DOM {
i2svg(params: { node: Node; callback: () => void }): void;
css(): string;
insertCss(): string;
}
到目前为止，我已经达到的最大值是由 font-awesome 制作的浏览器中的日志，在此代码之后带有以下信息“fontawesome.dom.i2svg()”：
fontawesome.dom.i2svg({ node: document.body, callback: callbacki2Svr });
function callbacki2Svr() { }
我已经尝试了很多（null 导致“Uncaught TypeError: Cannot read property 'querySelectorAll' of null”），现在我无法前进。有人有建议吗？
安装：
1）按照使用节点js的说明（[TOKEN]是我从购买中收到的密钥）：
npm i --save @fortawesome/fontawesome
npm config set @fortawesome:registry https://npm.fontawesome.com/[TOKEN]
Created a .npmrc file in the root of my project with the following content:
@fortawesome:registry=https://npm.fontawesome.com/[TOKEN]
npm i --save @fortawesome/fontawesome-pro-light
2) 更新 angular-cli 3) 使用 (ng b -aot) 重建应用程序 4) 启动项目。
先感谢您！
