How to make EUI part of Kibana packages?

Hello,
I'm running a development version of Kibana 7.10.2. Currently, I have a fork of EUI 29.3.2, with many custom components (eui/packages/) and themes (eui/src/themes).

Ideally, I want to submodule this fork in kibana/packages/elastic-eui with the awareness of @kbn/pm to do the job. I follow the instruction to make this kibana/packages/elastic-eui/package.json to have private: true.

However yarn kbn bootstrap throw lots of error regarding dependency version conflicts between kibana and eui:

ERROR [@elastic/eui] depends on [@elastic/datemath] but it's not using the local package. Update its package.json to the expected value below.
 info Additional debugging info:

 โ”‚ info actual: "@elastic/datemath": "^5.0.3"
 โ”‚      expected: "@elastic/datemath": "5.0.3"
 โ”‚      package: @elastic/eui (~/projects/kibana/packages/elastic-eui/package.json)
 โ”‚ info actual: "@elastic/eslint-config-kibana": "^0.15.0"                                  โ”‚=

 โ”‚      package: @elastic/eui (~/projects/kibana/packages/elastic-eui/package.json)

After fixing those it continues:

ERROR [single_version_dependencies] Multiple version ranges for the same dependency
      were found declared across different package.json files. Please consolidate
      those to match across all package.json files. Different versions for the
      same dependency is not supported.

      If you have questions about this please reach out to the operations team.

      The conflicting dependencies are:

@thompsongl - can you please assist?

Thanks

@thompsongl Any lights you can shed?
Also any alternatives to get the same result would be much appreciated.

What instructions did you follow?
I may need to ask someone with a better understanding of the Kibana package system, but we can start there.

I followed the readme in packages/ kibana/README.md at v7.10.2 ยท elastic/kibana ยท GitHub

I may need to ask someone with a better understanding of the Kibana package system

Yes, please. I understand the error because yarn installs all deps in root dir, and think there would be more steps to resolve them which I lack of knowledge of, as how it should work when installing deps from npm.

The problem you're running into is that EUI is using a published version of @elastic/datemath, where Kibana itself is using packages/elastic-datematch. You might be able to update the EUI dependency to use the same as Kibana - or just remove the dependency from the package.json and let it bubble up.

Looking at your other message, looks like there are going to be quite a few dependencies to deal with. You're probably best off publishing your own fork of EUI and updating the reference in your Kibana fork unless you want to and are able to do the work of resolving the conflicts.

I did try to remove/resolve the dependency versions, though major version changes such as

sass-loader
          ^10.0.1 => @elastic/eui
          ^8.0.2 => @kbn/interpreter, @kbn/optimizer, @kbn/ui-framework, x-pack
        style-loader

would produce issues. I observe yarn build does not work.
Publishing forked eui is our last resource, seems like it has to be.

Thank you all for your responses.
