@aayanqazi @flexzuu @eloquentbit There appears to be a problem with current versions of yarn when requesting to ignore optional dependencies – these failures are happening because transitive optional deps are causing the installation to fail. It’s not a bad idea to get the build dependencies set up (https://www.npmjs.com/package/windows-build-tools, python, etc.), it’s also possible to resolve this by uninstalling yarn and allowing CRNA to use npm (which sucks) but I am hoping to find a workaround that doesn’t have these issues…
