Hil*_*ard 2 html web typescript angular-material angular
当我单击工具栏图标时，我试图使用有角度的材料打开侧面导航。一切正常，直到我尝试实际打开导航栏，我收到错误：
由 /src/app/app.module.ts 中的 AppModule 模块导入的意外指令 'MatDrawer in @angular/material/sidenav/index.d.ts'。请添加@NgModule 注释。
这是 npm 模块 (package.json)：
"@angular/animations": "^9.1.11",
"@angular/cdk": "^9.2.4",
"@angular/common": "~9.1.11",
"@angular/compiler": "~9.1.11",
"@angular/core": "~9.1.11",
"@angular/forms": "~9.1.11",
"@angular/material": "^9.2.4",
"@angular/platform-browser": "~9.1.11",
"@angular/platform-browser-dynamic": "~9.1.11",
"@angular/router": "~9.1.11",
"jQuery": "^1.7.4",
"jquery": "^3.5.1",
"rxjs": "~6.5.4",
"tslib": "^1.10.0",
"zone.js": "~0.10.2"
这是我的 app.module：
import { MatDrawer } from '@angular/material/sidenav';
import { MatDrawerContainer } from '@angular/material/sidenav';
@NgModule({
declarations: [
AppComponent,
DressesComponent,
LoadingSpinnerComponent,
Toolbar,
ButtonToggle,
Sidenav
],
imports: [
BrowserModule,
AppRoutingModule,
HttpClientModule,
BrowserAnimationsModule,
MatTableModule,
MatSelectModule,
MatDialogModule,
MatInputModule,
MatToolbarModule,
MatIconModule,
MatButtonToggleModule,
MatDrawer,
MatDrawerContainer
],
providers: [DressesService, SidenavService],
bootstrap: [AppComponent]
})
export class AppModule { }
和 app.component.html：
<html dir="rtl" lang="he">
<toolbar></toolbar>
<side-nav></side-nav>
</html>
要导入组件和指令等，您需要导入它们的模块，而不是实际的组件和指令。所以你需要 importMatSidenavModule而不是MatDrawer, MatDrawerContainer：
import {MatSidenavModule} from '@angular/material/sidenav';
@NgModule({
declarations: [
AppComponent,
DressesComponent,
LoadingSpinnerComponent,
Toolbar,
ButtonToggle,
Sidenav
],
imports: [
BrowserModule,
AppRoutingModule,
HttpClientModule,
BrowserAnimationsModule,
MatTableModule,
MatSelectModule,
MatDialogModule,
MatInputModule,
MatToolbarModule,
MatIconModule,
MatButtonToggleModule,
MatSidenavModule //<-- this one
],
providers: [DressesService, SidenavService],
bootstrap: [AppComponent]
})
export class AppModule { }
