[2.0-beta13] Can't access ReactDOMServer

[mokahaiku]

First, thanks for all your effort working on this awesome project 🙇

Issue: when trying to add import ReactDOMServer from 'react-dom/server'; I get an error message:

ERROR  Failed to compile with 1 errors

This dependency was not found in node_modules:

* /../node_modules/react-dom/index.js/server

Did you forget to run npm install --save for it?
