OK - found the issue for me. I had a devDependency (an older version of kadira/storybook) that was depending on an old version of webpack 1.4.x - and that was what was being installed, not 2.5.x. I yarn removed the storybook package, yarn install and yarn start worked like a charm.

Seems like the order in package.json matters too. Putting storybook last in the dev dependencies seems to fix it for me.
