Yarn fails on transitive optional dependencies that aren't compatible with the current OS

[Daniel15]

Yarn handles this correctly for direct dependencies (ie. dependencies in the package.json of the app you're running Yarn on), but not for transitive dependencies (ie. dependencies of those dependencies).

Example package.json to repro on Windows:

{
  "name": "hello",
  "version": "0.0.1",
  "dependencies": {
    "chokidar": "1.6.0"
  }
}

Example package.json to repro on Linux or Mac OS X:

{
  "name": "hello",
  "version": "0.0.1",
  "dependencies": {
    "@daniel15/win-test-2": "0.0.1"
  }
}

chokidar has an optional dependency on fsevent, which only works on Mac OS. Similarly, @daniel15/win-test-2 has an optional dependency on @daniel15/win-test which only works on Windows.

This blocks installation of create-react-app, browserify and webpack on Windows (among other things) as they all have a dependency on either chokidar or fsevents

[Daniel15]

@kittens - Any ideas if this is an easy fix? I think it's blocking for launch given Windows and Linux users currently can't install packages that have a transitive dependency on fsevents.

[Daniel15]

Looks like this regressed at some point 😢 #1285

[kenotron]

I think this change fixed it half-way, fixing #1285 should bring it to completion. @kittens can you please take a look?

Ran into this issue today with winston-winlog3 in optionalDependencies on macOS.

and this is what the error shows

Was this properly resolved? I'm interested in switching my team's process to yarn, but I'm running into similar issues here.

I'm attempting to setup workspaces, because we have a monrepo setup, and the source registry is a private registry in Azure DevOps. The problematic package is our own native node module in the workspace (it has "os": [ "darwin" ] in the package.json). We have another workspace package that optionally includes it ("optionalDependencies": { "our-native-package": "1.0.0" }). Yarn fails to install with an error saying our-native-package is incompatible.

Was this ever fixed? I'm having this issue right now in 2021.
