据我所知,@angular/material现在包含导入所需的唯一模块MaterialModule。我尝试从@angular2材质/图标导入MdIconModule,但没有成功。我做错了什么?
提前感谢按照yurzui的建议导入MaterialModule,并在承诺返回后创建组件。谢谢你,尤瑞

自从@javahaxxor的回答以来,在新版本的角度材质中,情况发生了变化。我已经通过导入与我在AppModule
中相同的模块解决了这个问题(这里我还需要表单):
md图标在最新版本的Angular Material中不再可用。所有标记/元素现在都以“mat”而不是“md”作为前缀。。因此,
。变成<代码>
import {
MatButtonModule,
MatCardModule,
MatIconModule,
MatInputModule,
MatProgressSpinnerModule,
MatDialogModule,
MatCheckboxModule
} from '@angular/material';
// ... not important
beforeEach(async(() => {
TestBed.configureTestingModule({
declarations: [ WelcomeComponent ],
imports: [
NoopAnimationsModule,
FormsModule,
ReactiveFormsModule,
MatButtonModule,
MatCardModule,
MatIconModule,
MatInputModule,
MatProgressSpinnerModule,
MatDialogModule,
MatCheckboxModule
],
providers: [

})
.compileComponents();
}));
