Uncaught TypeError: Class constructor Platform cannot be invoked without 'new'

Question

I've installed the Angular CDK in order to use PrimeNG's dropdown component but it throws an error.

I've added this in my app.module.ts:

import {DropdownModule} from 'primeng/dropdown';

And installed the Angular CDK by simply typing in the following:

npm install @angular/cdk --save

I had the same issue. Check your cdk version in your package.json

I solved installing an older version of cdk 10:

npm i @angular/[email protected] --save
