angular - 无法绑定(bind)到 'icon'，因为它不是 'fa-icon' 的已知属性

Question

我正在使用 ngx-share's Share Button Directive在我的项目中。但是，我似乎无法使用图标。如果我尝试使用这样的图标:

<button mat-fab shareButton="telegram" [style.backgroundColor]="share.prop.telegram.color">
  <fa-icon [icon]="share.prop.telegram.icon" size="lg"></fa-icon>
</button>

我得到的是以下错误:

Uncaught Error: Template parse errors:
Can't bind to 'icon' since it isn't a known property of 'fa-icon'.
1. If 'fa-icon' is an Angular component and it has 'icon' input, then verify that it is part of this module.
2. If 'fa-icon' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message.
3. To allow any property add 'NO_ERRORS_SCHEMA' to the '@NgModule.schemas' of this component. ("on mat-fab shareButton="telegram" [style.backgroundColor]="share.prop.telegram.color">
    <fa-icon [ERROR ->][icon]="share.prop.telegram.icon" size="lg"></fa-icon>
  </button>

我该如何解决这个问题？

我将 ShareModule 添加到导入列表中:

@NgModule({
  imports: [
    //..
    ShareModule.forRoot()
  ]
})

我的组件还根据需要注入(inject) ShareButtons 对象:

export class GroupComponent {    
  constructor(public share: ShareButtons) {
  }
}

编辑您还可以导入
ShareButtonModule 已经导出 FontAwesomeModule。

原始答案

假设你已经安装了 font awesome npm 包，你需要将 FontAwesomeModule 添加到你的模块的导入中

import { FontAwesomeModule } from '@fortawesome/angular-fontawesome';

@NgModule({
 //...
imports: [
     //...
   FontAwesomeModule
  ],
})
export class AppModule { }  

看这里的例子
