Webpack error on static build

Describe the bug Webpack loader error when building a static site using build-storybook, with default setup:

./stories/index.stories.js 9:55
Module parse failed: Unexpected token (9:55)
You may need an appropriate loader to handle this file type.
| import { Button, Welcome } from '@storybook/react/demo';

I have tried tweaking webpack.config.js in .storybook, but can’t figure out the correct settings that will get this to build correctly. Thanks for any assistance with this.

To Reproduce Steps to reproduce the behavior:

1. Fresh repo (cloned from react-boilerplate, as per quick start instructions)
2. npx -p @storybook/cli sb init
3. npm run build-storybook

Expected behavior Storybook static site builds correctly. npm run storybook works fine locally, but cannot build a static site. Attempting to deploy to gh-pages using storybook-deployer has the same error (deploys successfully, but storybook is broken).

System:

• OS: Windows 7
• NodeJS 10.15.0
• Storybook 4.1.11
• React 16.6.0
• Webpack 4.23.1

Hey there, it’s me again! I am going close this issue to help our maintainers focus on the current development roadmap instead. If the issue mentioned is still a concern, please open a new ticket and mention this old one. Cheers and thanks for using Storybook!
