app.moduleにMatDialogModuleをインポートできません

Question

私は角度の初心者で、angularマテリアルダイアログボックスを使用しています。最初に、プロジェクトにマテリアルを追加し、@angular/material。

（import { MatDialogModule } from '@angular/material/dialog';））app.module.ts、プロジェクトのコンパイル時にエラーが発生する

 ERROR in node_modules/@angular/cdk/coercion/array.d.ts(10,60): error
 TS1005: ',' expected.
 node_modules/@angular/cdk/coercion/array.d.ts(10,61): error TS1005:
 ',' expected. node_modules/@angular/cdk/coercion/array.d.ts(10,75):
 error TS1144: '{' or ';' expected.
 node_modules/@angular/cdk/coercion/array.d.ts(10,77): error TS1011: An
 element access expression should take an argument.

どうして？
