Issue of missing dependencies

[ShivamShokeen]

The target entry-point "@ngez/core" has missing dependencies:
 - @angular/cdk/a11y
 - @angular/cdk/portal
 - @angular/cdk/keycodes
 - @angular/cdk/overlay

I ran this npm i @ngez/core --save command and it was giving error of missing dependencies. When I run npm i @angular/cdk/a11y --save gives an error of

error Could not install from "@angular\cdk\a11y" as it does not contain a package.json file.
