Experiencing something similar to this... I can run react-docgen
fine from the CLI interface, but trying to run it via code (webpack + dev-server) triggers the error. The actual error is:
TypeError: pluginList.indexOf is not a function at Parser.loadPlugins (index.js:1620)
As @oliviertassinari described originally, the pluginList
-parameter is { jsx: true, flow: true }
- Which is apparently gotten from babylon
. Obviously said parameter is an object, not an array, which causes the indexOf
-check to fail.
I've tried upgrading all my prop-types
and babel
-related packages to their latest versions, but that didn't help. npm list babylon version
reveals that I have [email protected]
everywhere else, except react-docgen
still has it as [email protected]
. Could this be the issue?

react-docgen@v2 uses babylon 5 and that will not change. We also have a beta version v3.0.0 which uses babylon 7, you can try that.

What is the Babylon version you are using here? This rather seems to be a configuration error or an inconsistent state of your nodes_module folder. Sure, we could upgrade to a newer version of Babylon, but that shouldn't be necessary. Whatever Babel version you are using shouldn't impact react-docgen and vice versa.

That's what I though, I'm gonna investigate more on this.

I'm using the latest release of react-docgen. I'm not using directly babylon.

@fkling Thanks for your help! It was indend an issue with my dependences. I had two version of babylon (v5, v6), and my webpack config wasn't resolving the good one 😁.

Is there any ETA for the Babel 6 upgrade? I am running into the same issue and ideally I'd rather avoid playing with module resolution in web pack.

@yrashk: There is no plan to upgrade babylon atm. Can you share information about your setup? You have to think of react-docgen
as a standalone tool / library (just like eslint). Whatever setup you have shouldn't impact it, and there shouldn't be anything you have to configure differently.
However, there could be an issue when npm didn't install the correct dependencies. I guess one solution to avoid these issues could be to use bundledDependencies
.

@danez Material-UI has been relying on the v3.0.0 beta for months now. It's working great.
from react-docgen.
@danez tried v3-dev
- But it seems that branch only has the CLI interface available (at least when installing via NPM)? Anyway I moved on to making a CLI workaround since the NodeJS API is going nowhere.
from react-docgen.
just install with npm the latest beta
npm install react-docgen@next
Installing the branch directly won't work, as there are build steps involved when releasing.
