Running freshly installed storybook with yarn run storybook in my Create React App based application yields...

ERROR in ./src/stories/index.js
Module build failed: SyntaxError: Unexpected token, expected , (8:13)

@natdm could you specify your OS and which way you installed Storybook (via getstorybook or manually)?

[natdm]

Apologies. macOS and yes, getstorybook.

[usulpro]

Do you have any custom .babelrc or webpack.config.js in your project?
Is it a fresh install of CRA + getstorybook or you installed it to an existing project?
In this case, could you try this steps to check is it reproducible with default config?

[natdm]

To update, I blew out storybook, re-installed it after upgrading everything and it seems to work fine now.

Glad you sorted it out! Closing now, but feel free to re-open if you need to revisit.
