I would say this is a bug..

What is the current behavior?

Angular compiler outputs the following after changing the package management to yarn (from npm):

If the current behavior is a bug, please provide the steps to reproduce.

What is the expected behavior?

I would think that there would be no changes needed in our code, when the package manager is changed. As I understand, yarn still works on npm-"backend"? There is no more information printed and I don't know what to do, because I have no deeper knowledge of how yarn is working with it's cached dependencies, because I'm "only" a angular(5) developer who is using yarn for package management.
What would be the way to proceed? I've switched from npm to yarn, because sometimes uncontrollable errors appeared when npm re-installs were done.. but the dependencies were correct when npm was used.

Please mention your node.js, yarn and operating system version.
