But if I add "acorn": "^6.0.5" to dependencies, it works.

I am not sure how to fix it. Leaving it here as a workaround. Maybe I switch back to Yarn.

@steida I don't think this is an issue we can fix on our end. We tried adding "acorn": "^6.0.5" to next's dependencies (#6137), but it doesn't seem to be making a difference.
