You need to import these modules separately:

import { MatSliderModule } from '@angular/material/slider';
import { MatSnackBarModule } from '@angular/material/snack-bar';
import { MatTableModule } from '@angular/material/table';
import { MatTabsModule } from '@angular/material/tabs';
import { MatToolbarModule } from '@angular/material/toolbar';

And so on. Then, it should work fine.

If you check node_modules/@angular/material/index.d.ts you see an almost empty file but a comment. This file does not export any Angular Material module hence the error.

For example node_modules/@angular/material/toolbar/index.d.ts:

/**
 * Generated bundle index. Do not edit.
 */
export * from './public-api';

//# sourceMappingURL=index.d.ts.map

And then in node_modules/@angular/material/toolbar/public-api.d.ts you find the accordant module:

/**
 * @license
 * Copyright Google LLC All Rights Reserved.
 *
 * Use of this source code is governed by an MIT-style license that can be
 * found in the LICENSE file at https://angular.io/license
 */
export * from './toolbar-module';
export * from './toolbar';
