我遵循了官方指南并创建了app-theme.scss以下内容:

@import '~@angular/material/theming';    
@include mat-core();    
$candy-app-primary: mat-palette($mat-indigo);
$candy-app-accent:  mat-palette($mat-pink, A200, A100, A400);    
$candy-app-warn:    mat-palette($mat-red);    
$candy-app-theme: mat-light-theme($candy-app-primary, $candy-app-accent, $candy-app-warn);    
@include angular-material-theme($candy-app-theme);

内容styles.css:

@import './app-theme.scss';

但是,我在编译期间总是遇到以下错误:Module not found: Error: Can't resolve '@angular/material/theming'.我该怎么做才能让它发挥作用？
