It worked on my machine™

It looks like there's been a bad build of npm package core-js-compat. This is a deep-down dependency of Babel. Lots of things will be affected, things that use Babel.

You will experience this problem if you have core-js-compat v.3.4.6. You can check this by doing npm list core-js-compat. The problem is apparently fixed by v.3.4.7, which was pushed out pretty quickly, about half-an-hour later, but unfortunately it takes a while to spread out through the repositories. You can either wait until an npm update gets you v.3.4.7 or you can go manually download v.3.4.7 if you want to get going right away.

This is a bug with core-js-compat v3.4.6, but already the fix has gone with v3.4.7. See https://github.com/zloirock/core-js/issues/712 for more detail.
