Problems caused by the introduction of Vue in laravel5.3

What effect does the app.js section under resureces have on vue?
Introduction problems will occur after Vue.js is introduced on the page, but it is correct after commenting and re-gulping

The framed code is to register a global component and then instantiate a vue as a loading point. The example component can be referenced in the page.
If it’s not correct, check to see if the imported path is correct.
