change babel.config.js presets: [[‘@vue/app’, { useBuiltIns: ‘entry’ }]]

It seems to be due to https://github.com/babel/babel/pull/9616

I fixed it by adding "@babel/parser": "<7.4.0", to my dependencies. That forces your app to resolve to @babel/parser 7.3. And with that the problem is fixed. I’ll revisit this in a month or two once the Babel people fix the problem.

npm ls @babel/parser
