Angular 5材质微调器不起作用

Angular 5 Material Spinner is not working

app.module.ts

app.module.ts

import { MatProgressSpinnerModule } from '@angular/material/progress-spinner';
@NgModule({
  imports: [
    MatProgressSpinnerModule
  ]})

component.ts

component.ts

import { MatSpinner } from '@angular/material';

component.html

component.html

<mat-spinner></mat-spinner>

我缺少任何配置吗??

am I missing any configuration.?

在参考中，它正在为Spinner生成SVG文件，但是我没有在mat-spinner标签内看不到任何东西.

In Reference, it's generating an SVG file for Spinner but I don't see anything inside mat-spinner tag.

推荐答案

我尝试添加给出的mat-spinner示例，并且效果很好.我能看到的唯一区别是导入进度微调器模块的方式，而不是从特定路径导入它的方式:

I tried to fork the mat-spinner example given and that works perfectly. The only difference that I could see is the way you import the progress spinner module instead of importing it from a specific path do this:

  import { MatProgressSpinnerModule } from '@angular/material';

当mat-spinner扩展了matprogressSpinner时，您不需要在组件内部导入任何内容.

You don`t need to import anything inside your component as mat-spinner extends matprogressSpinner.

在相关html内执行您正在做的事情，即

Inside the relevant html just do what you were doing i.e.

<mat-spinner></mat-spinner>
