Latest react-styleguidist only works with a very narrow dependency on react-docgen

[matthew-dean]

Current behavior

Since updating Styleguidist to the latest version, I've been getting these errors:

Warning: Cannot parse src/common/presentation/elements/Anchor/Anchor.js: RangeError: Maximum call stack size exceeded

It usually means that react-docgen does not understand your source code, try to file an issue here:

Warning: Cannot parse src/common/presentation/elements/Avatar/Avatar.js: RangeError: Maximum call stack size exceeded

It usually means that react-docgen does not understand your source code, try to file an issue here:
https://github.com/reactjs/react-docgen/issues

I found that if I tried a different react-docgen dependency, (Beta 6 AND RC 1), they both fail.

To reproduce

Run npm install react-docgen@3.0.0-rc.1. Try to build the Styleguide

Expected behavior

Styleguidist should work with newer versions of react-docgen other than just the narrow matching version of beta 12.

Confirmed (by installing different versions of Styleguidist) that Styleguidist started failing with versions of react-docgen other than beta12 at react-styleguidist version 7.1. Styleguidist 7.0.x (checked with 7.0.20) does not have this issue.

Not sure we can do anything on our side ;-/

[matthew-dean]

@sapegin Well, maybe. But Styleguidist 7.0 didn't have this issue. So, yes, it may be a react-docgen bug, but 7.0 didn't trigger it, or Styleguidist is calling something in react-docgen which is causing an error, but only for those other versions. So that could be something to look at; what changed after 7.0. Because, considering react-docgen is on RC1, it's likely that this will continue to be an issue and Styleguidist may never be able to upgrade without addressing or circumventing the issue as it did before 7.1.

Can anyone share an example of a file which fails? I tried reproducing this error in react-docgen, but so far had no luck.

We released react-docgen@3.0.0-rc.2, it has the latest version of recast and babel and some fixes. Let me know if that makes it any better.

@danez Hi, thanks! react-docgen@3.0.0-rc.2 fixes the issue for me, have opened a PR to update to it.

this actually caused my SG to stop working when I upgraded to v8.0.5 (v8.0.4 works perfectly fine). This is what I started to see with v8.0.5:

Cannot find module 'react-docgen/dist/babylon'
npx styleguidist server --open exited with code 1
