Those reproduction steps are not steps describing how to reproduce. You just copied the output of the console after the steps.

This is likely permissions-related.

I operate step by step according to the official document, how do I solve the problem of permissions-related?

@skillnull, this issue is a symptom of issue #3664 which you also commented on to say you have that problem as well. That issue #3664 was fixed and closed about a month ago so update your version of Vue CLI and all should be ok.

This bug can be closed.
