I needed to build a custom release and had the same issue. However, building from 2.0.8 works (4973168), it looks like building setup was updated and something broke.

I also encountered this problem. Updating the dev dependency "babel-preset-es2015-rollup" to the most recent version (3.0.0) fixed it.
