Using the export keyword between a decorator and a class is not allowed

I'm attempting to migrate react-styleguidist from v8 -> v9 and noticed that react-styleguidist@8.0.5 and beyond starts showing errors in the terminal:

You can now view your style guide in the browser:

This warning does not show on react-styleguidist@8.04. I think styleguidist/react-styleguidist#1200 may be the culprit. Would this be a react-docgen issue? /cc @danez

react-docgen in 3.0.0 changed to use the new decorators proposal be default. Which in retrospect was a big mistake as it is already abandoned and a complete new specification exists.🙄

But anyway, in order to fix this issue you are having, you probably will have to wait till styleguidist/react-styleguidist#1288 is merged and released. In the latest version of react-docgen we now correctly read babel configs, which in your case would enable the decorators-legacy support in your project instead of the "new-yet-abandonend" decorators proposal.
I'm sorry for the inconvenience.

Thank you for the quick response. No worries, there's no rush from my end :)

@danez I am getting the same exact errors when trying to migrate to v9.1.16. Any idea if react-docgen fixed the issue?
