I spent hours on this error changing node and quasar versions etc. I always used yarn and never this error until now.
For me @bigzhu 's suggestion worked - simply removing .babelrc which I believe should never have been there.
I think I was reusing a previous project dir after clearing it out first with rm -rf * which I now know doesn’t include .hidden files!
