If the current behavior is a bug, please provide the steps to reproduce.

yarn add chokidar

What is the expected behavior?

Incompatible optional dependency should be excluded completly.

Please mention your node.js, yarn and operating system version.

Same here on my production server, where as on my MacOS no issue with npm or yarn. I'm using latest nodeJs tried with 6 and 8, and i'm using latest Yarn 1.2.1.

I am ending up with a lot more MB in node_modules installing with yarn. I am certain that one big factor is fsevents when installing chokidar, same as the OP is facing. I am on ubuntu 16.04, node 6.2.2. yarn seems to install all optional dependencies, regardless of platform support.

Same issue on win10 and yarn version is 0.16.1, also resemble error Not compatible with your operating system or architecture: [email protected] on npm.

This should have been fixed by #525, but it looks like it regressed at some point 😢 . ~~You can replicate the issue on a non-Windows environment by running yarn add @daniel15/win-test-2~~ (edit: sorry, I was incorrect)

Daniel15 on 28 Oct 2016

@Daniel15, I don't think that module works as it specifies the os field so it errors on the main package (for non-Windows users), before it gets to the optionalDependencies.

But if I exclude the platform check for win-test-2 explicitly, this is the output I get:

$ yarn add @daniel15/win-test-2
info No lockfile found.

Verified the optionalDependency module was installed too:

$ ls node_modules/@daniel15
win-test   win-test-2

It is interesting that it reports excluding it from installation, but installs it anyways.

wyze on 28 Oct 2016

@wyze - Oops, my mistake! Sorry for the misleading comment. I just realised my test package was configured incorrectly.

Daniel15 on 28 Oct 2016

In case it helps, running yarn install --production resolved the fsevents error for me on linux using version 0.16.1. With the production flag I just get a warning that it is skipping fsevents.

Done in 12.34s.

Repeated installation attempts eventually makes it happy, but clearing out node_modules and package.json and doing a fresh install of chokidar reliably fails.

Update:
It looks to me like what is happening is that PackageCompatibility.check is merely printing a warning for optionalDependencies that fail the validation check. It is not actively removing them from the queue so PackageInstallScripts.init tries to run the install script for fsevents anyway.

@kriscarle I think that might be a fluke. I tried installing chokidar with the production flag and it still failed.

I tried use yarn and i faced with the issue:

error [email protected]: The engine "node" is incompatible with this module. Expected version "0.8.x".
error Found incompatible module

node@6
yarn@latest (v0.17.6)
mac@latest (sierra)

When i use npm, it was work normally.

on the one hand, new behaviour is good,
on the other hand, old package is deep nested and i cannot update it, so i cannot use yarn

Same issue as @gkatsanos

erikryanmoore on 25 Nov 2017

@MatrixOfDeath - Any lines with npm ERR! at the start are coming from npm, not Yarn.

@gkatsanos That just looks like a warning, not an error. It's legitimate, as fsevents doesn't work on Linux (only on MacOS).
