5. Only the app, and bar works

What is expected?

The foo watcher should be invoked.

What is actually happening?

Only the app and bar watchers are invoked.

I'm not really sure this is a bug or not.

If not, what can I do to achieve same feature?

Thanks~

This is normal and to avoid it you need to link vue in both libraries and applications that use linked libraries. There will be a note on docs.

You can also use yarn pack to avoid the issue, you should take a look at existing issues for a full command
