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
angular-cdk angular

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/cdk@9.2.4 --save

In case someone has the same issue while trying to implement material design with angular material, rollback both material and cdk packages to an older version with:

npm i @angular/cdk@9.2.4 @angular/material@9.2.4 --save

I hope someone proposes a better approach that enables using the latest versions.

In file tsconfig.json,

add this line- "target": "es5",
