v-calendar-issues-502

testbed environment to figure out the build failure on v-calendar

see: nathanreyes/v-calendar#502

steps to reproduce the issue

$ git clone 'https://github.com/no6v/v-calendar-issues-502.git'
$ cd v-calendar-issues-502
$ yarn install
$ yarn build
$ ruby -run -e httpd -- dist
(visit http://localhost:8080/)

In my environment, it seems good at this time.

Let's make the issue appear:

• edit babel.config.js to modify the regenerator option to true
• yarn build

This is what the error (just warning in this case, though) in question. Reload the browser, and you will see the message below on your browser console.
