Angular2-在路由中在每個模塊上導入插件？

Question

我是否必須導入例如： "import { Angular2FontawesomeModule } from 'angular2-fontawesome/angular2-fontawesome'" ， import { MaterialModule } from '@angular/material'; ...兩個模塊？ （home.module.ts和app.module.ts）

如果我想在我的登錄名和dashborad組件中使用它？

因為我遇到類似“未處理的承諾拒絕：模板解析錯誤：由於它不是'fa'的已知屬性而無法綁定到'name'的錯誤。”

-app
  -login
    *login.component.html
    ...
  -home
    -dasborad
      *dashboard.component.html
      ...
    -users
      *user.component.html
      ...
    *home.component.html
    *home.component
    *home.module
  -toolbar
    *toolbar.component.html
  *app.component
  *app.module

您可以使用所有這些公共導入創建一個公共/共享模塊，然后將共享模塊導入到您想要相同功能的每個模塊（在Imports數組中）。 請參考此鏈接 。
