Cannot find module '.pnpm/package.json' when running ember-mapbox-gl with pnpm

[johanrd]

1. Clone https://github.com/johanrd/ember-mabox-gl-pnpm-repro or create a fresh ember app with pnpm:

   ember new ember-mabox-gl-pnpm-repro --skip-npm
   cd ember-mabox-gl-pnpm-repro
   pnpm install
   pnpm add ember-mapbox-gl mapbox-gl

2. Run pnpm start and experience the following error:

   Cannot find module '.pnpm/package.json' from '/Users/me/ember-mabox-gl-pnpm-repro'

Possibly related to dynamic imports?

[kturney]

Hi @johanrd, thanks for the issue.

I've never used pnpm myself.

Does it seem at all related to https://github.com/ef4/ember-auto-import/issues/353?

[johanrd]

@kturney FYI: referring to this comment, the error for pnpm (and probably other modern package managers like yarn 3) was in this line: https://github.com/kturney/ember-mapbox-gl/blob/master/index.js#L21, where mapbox-gl/package.json was accessed relative to the context of ember-cli instead of ember-mapbox-gl.

I tried to remove the whole included function, and can verify that ember-mapbox-gl is no longer blocking build through pnpm. (syles needed to be imported otherwise through e.g. @import "mapbox-gl/dist/mapbox-gl.css", though)
