Answer
Your @angular/material command is not install all the dependency currently that why throw error try to run @angular/material @angular/cdk @angular/animations install angular material.
For old version use:-
npm install --save @angular/material @angular/cdk @angular/animations
For latest version use:-
ng add @angular/material
For more information visit official site of angular material https://material.angular.io/guide/getting-started
The ng add command will install Angular Material, the Component Dev Kit (CDK), Angular Animations and ask you the following questions to determine which features to include
Edit: fixed dashes for npm install command
