Help with custom Rule sets and Yarn v2

[rayterrill]

hello! i'm a n00b to spectral and looking for a little help getting going with publishing and consuming specs with yarn. is there a best channels for this?

i tried to publish a yaml ruleset using the npm guide here: https://meta.stoplight.io/docs/spectral/ZG9jOjI1MTky-sharing-and-distributing-rulesets#npm, which didnt quite work in consuming it into a project with yarn v2. backed up and built the actual example from https://meta.stoplight.io/docs/spectral/ZG9jOjI1MTky-sharing-and-distributing-rulesets#npm, and it's basically the same error. publishing seems to work fine - it's consuming where i'm struggling.

in my consuming project, i've got this in my package.json:

{
  "name": "go-openapi",
  "packageManager": "[email protected]",
  "dependencies": {
    "@myco/spectral-test": "^0.0.1"
  }
}

and i've got a .spectral.yml in my repo:

extends: 
  - @myco/api-standards-linting

when i do: spectral lint openapi.yaml, i see:

Error running Spectral!

Pretty sure I tracked this down - looks like yarn v2 by default uses PnP mode - not node_modules which spectral seems to expect. Fixed by flipping yarn back into node_modules mode by adding this to my project's .yarnrc.yml:

nodeLinker: node-modules
