Does it proceed with installation after that?
fsevents is a Mac-only dependency, if it is not marked as optional then you can't install the dependency on a Windows machine.

A way around is to use --ignore-engines flag IIRC.

[thisVioletHydra]

what about optionalDependencies?
Is it worth it to put my fsevents@ there or not?

[bestander]

Yes, fsevents should be an optional dependency

[Daniel15]

Yes, this is not a Yarn bug. You're specifying fsevents as a devDependency, but fsevents doesn't work on Windows. You'll need to make it an optional dependency, otherwise you'll be unable to yarn install on Windows.
