Please use forum for questions and help requests. You need install angular/cdk module,
npm install @angular/cdk --save
You can look in https://www.primefaces.org/primeng/#/multiselect .

This bug shouldn't be closed because:

• I'm not using multiselect, hence I shouldn't be concerned with cdk
• this is a backwards-incompatible change, which breaks semver versioning
• if this is a required dependency, it should be explicitly specified for npm

I agree with @krojew mostly for the second and third point. The other issue related to this was closed and has a commit associated with it to move @angular/cdk to the peer dependencies, but that commit was rejected by the CI tool and never entered the master branch.
