无法从@angular/forms@^9.0.0添加FormsModule、ReactiveFormsModule

以上是我的Package.json依赖项版本。我使用的是angular 9.0.0。我试图在app.module.ts中添加formmodule，但无法执行此操作。即使来自“@angular/platform-browser”包的BrowserModule也在同一文件中显示错误。 下面是我的应用程序模块代码

> "dependencies": {
>     "@angular/animations": "^9.0.0",
>     "@angular/cdk": "^9.0.0",
>     "@angular/common": "^9.0.0",
>     "@angular/compiler": "^9.0.0",
>     "@angular/core": "^9.0.0",
>     "@angular/forms": "^9.0.0",
>     "@angular/material": "^9.0.0",

提供应用程序模块代码。确保您已在

app.module.ts

@varundhariyal的导入部分添加了

BrowserModule，FormsModule

，我已编辑了我的查询并将应用程序模块代码放在那里。请显示您收到的错误消息。module'./.\node\u modules/@angular/platform browser/animations“'没有导出成员'BrowserAnimationsModule'。ts（2305）

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule, ReactiveFormsModule } from '@angular/forms';
import { AppComponent } from './app.component';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { SearchPageComponent } from './search-page/search-page.component';
import { SearchPageService } from './search-page/search-page.service';
import { HttpClientModule } from '@angular/common/http';
@NgModule({
  declarations: [
    AppComponent,
    SearchPageComponent   
  ],
  imports: [
    BrowserModule,BrowserAnimationsModule,FormsModule,
    ReactiveFormsModule,HttpClientModule
  ],
  providers: [SearchPageService],
  bootstrap: [AppComponent]
})
export class AppModule { }
