New*_*Nik 7 typescript angular-material angular mat-icon
我有一个 Angular 项目,我试图在其中使用 Angular 材质库。在我的app-routing.module我有这样的代码:
import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';
import { SndComingSoonPageComponent } from './feature/pages/snd-coming-soon-page/snd-coming-soon-page.component';
const routes: Routes = [
{ path: '', pathMatch: 'full', component: SndComingSoonPageComponent },
];
@NgModule({
imports: [RouterModule.forRoot(routes)],
exports: [RouterModule],
})
export class AppRoutingModule {}

我正在SndComingSoonPageComponent尝试使用MatIconModule,但无论我在哪里导入它,我仍然无法使用它。
这是我的app.module.ts:
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { CoreModule } from '@core/core.module';
import { WidgetModule } from '@widget/widget.module';
import { FeatureModule } from '@feature/feature.module';
@NgModule({
declarations: [AppComponent],
imports: [
BrowserModule,
AppRoutingModule,
BrowserAnimationsModule,
CoreModule,
FeatureModule,
WidgetModule,
],
providers: [],
bootstrap: [AppComponent],
})
export class AppModule {}

我不明白。我应该在哪里导入MatIconModule以便我的comingSoonPageComponent 能够使用它?实际上,我如何确定哪个页面正在使用哪个模块?
您必须导入声明使用该材料设计功能的组件的材料模块。
就你而言,是的SndComingSoonPageComponent。
搜索您在该模块中声明SndComingSoonPageComponent并导入的模块MatIconModule。
例子:
import {SndComingSoonPageComponent} from '.......';
@NgModule({
declarations: [
AppComponent,
SndComingSoonPageComponent \\ component which uses module
],
imports: [
BrowserModule,
BrowserAnimationsModule,
HttpClientModule,
AppRoutingModule,
CoreModule,
MatIconModule \\ module
],
bootstrap: [AppComponent],
schemas: [CUSTOM_ELEMENTS_SCHEMA]
})
export class AppModule {
}
