Angular 5 字体真棒 5
Angular 5 with Font Awesome 5
经过一些研究，包括阅读 , documentation 等，我无法推进 Angular 5 App 和 Font-Awesome 5 (Pro) 之间的集成。
问题：图标不显示。

在我的研究过程中，我了解到我需要指定我需要使用的（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 中我需要调用 i2svg 方法来负责让奇迹发生：
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，我必须在其中告知以下数据：
export interface DOM {
i2svg(params: { node: Node; callback: () => void }): void;
css(): string;
insertCss(): string;
}
到目前为止，我达到的最大值是在浏览器中由 font-awesome 生成的日志，其中包含以下信息 "fontawesome.dom.i2svg()" 在此代码之后：
fontawesome.dom.i2svg({ node: document.body, callback: callbacki2Svr });
function callbacki2Svr() { }
我已经尝试了很多（"Uncaught TypeError: Cannot read property 'querySelectorAll' of null" 中的结果为空），但现在我无法前进。有人有什么建议吗？
安装：
1) 按照 use node js 上的说明进行操作（[TOKEN] 是我购买时收到的密钥）：
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) 更新了 angular-cli
3) 使用 (ng b -aot) 重建应用程序
4) 启动项目。

但是，@daniel-santana 告诉我们，这不可能集成到他们的大型应用程序中。
所以我能给你的最好建议是不要使用 SVG with JS 方法。它使用了一些高级功能，例如 requestAnimationFrame 和 MutationObservers，这些功能在 Angular 中表现不佳。如果您无法重构您的应用程序以使用新的 SVG 格式（这是 Font Awesome 5 中的新格式），请坚持使用 Web Fonts. Web Fonts for version 5 work just like web fonts in version 4. The upgrade to 5 would involve changing names for any of the icons that have been renamed. We have detailed docs here.
