已解决，少引了一个mudule

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { MatSliderModule } from '@angular/material/slider';
import {MatSidenavModule} from '@angular/material/sidenav';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';

import { AppComponent } from './app.component';
import { AppRoutingModule } from './app-routing.module';
import { HomeComponent } from './home/home.component';

@NgModule({
  declarations: [
    AppComponent,
    HomeComponent
  ],
  imports: [
    BrowserModule,
    AppRoutingModule,
    MatSliderModule,
    MatSidenavModule,
    BrowserAnimationsModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }
