Question

我最近安装了font-awesome，可以在组件上放置一些图标。安装后，这些图标均无效，并且我还丢失了所有前端视觉效果。仅显示导航栏和页脚。它编译良好。但是我什么也看不到。我在http://localhost:4200/teams/1/RCB上有一个运行良好的页面我试图将那些字体真棒的图标放入http://localhost:4200/teams/ 这是team-list-component-html 首先，我会收到诸如无法绑定到“大小”的错误，因为它不是“ fa”的已知属性。（“ 如果我从该错误的html文件中删除了所有代码，则会在http://localhost:4200/teams/1/RCB

上加载的主要组件上出现白色的空白屏幕

尝试安装和卸载font-awesome，这给了我更多错误检查了所有approute，一切似乎都很好。

Answer 1

检查选择器名称的FontAwesome图标。

Answer 2

它应该是fa-icon，并且如果您要提供静态大小，则不要使用单向数据绑定。

应该是这样的：

<fa-icon class="red-icon" size="2px" [name] = " 'plus' " [border]="false" [pull]="'right'" routerLink="/teams/add"></fa-icon>
