It seems to be related to this node change: nodejs/node#31625
However, this is not really reproducible since we do not have package-lock.json checked in, hence the versions are not locked down. On my end, this was fixable by one of:
rm -rf node_modules package-lock.json && npm i ORnpm up
Both of these installed newer versions of the dependencies than the minimum versions listed in package.lock. Before trying the above I had:
$ npm out

I briefly searched the babel core and babel loader release notes, but didn't see anything. In any case, we should bump the minimum babel deps.
