File to import not found or unreadable: foundation/foundation-global

When I performed a

bundle update zurb-foundation

lately (I updated from 4.1.1. to 4.2.1), I got the error message that a foundation import was missing.

After digging around a bit and reading https://github.com/zurb/foundation/issues/1840, I changed

@import "foundation/foundation-global";

(e.g. in app/assets/stylesheets/_settings.css.scss to

@import "foundation/variables";

and everything worked fine again
