Error when installing angular material using CLI environment

Question

I work with angular8 and I want to install angular material. First, I entered the following command in the CLI environment.

PS F:\Learn\PersonalWebSite\PersonalWebSite> ng add @angular/material
Installing packages for tooling via npm.
? Choose a prebuilt theme name, or "custom" for a custom theme: Indigo/Pink        [ Preview: https://material.angular.io?theme=indigo-pink ]
? Set up global Angular Material typography styles? Yes
? Set up browser animations for Angular Material? Yes
UPDATE package.json (1385 bytes)
√ Packages installed successfully.
UPDATE src/app/app.module.ts (950 bytes)
UPDATE angular.json (3943 bytes)
UPDATE src/index.html (540 bytes)

2: import in app.module.ts:

import { MatSliderModule } from '@angular/material/slider';
imports: [
    MatSliderModule
  ]

Error in TERMINAL:

 ERROR in node_modules/@angular/platform-browser/animations/animations.d.ts:37:22 - error NG6002: Appears in the NgModule.imports of AppModule, but could not be resolved to an NgModule class.

    This likely means that the library (@angular/platform-browser/animations) which declares BrowserAnimationsModule has not been processed correctly by ngcc, or is not compatible with Angular Ivy. Check if a newer version of the library is available, and update if so. Also consider checking with the library's authors to see if the library is expected to be compatible with Ivy.

    37 export declare class BrowserAnimationsModule {
                            ~~~~~~~~~~~~~~~~~~~~~~~
