See: twbs/bootstrap#40849. It appears there's a complicated web of constraints that means we may have to live with this. Some work-arounds are given in this message.

As I understand it, it's just a deprecation warning, so nothing is broken (yet). I recently rebuilt the test apps for this gem, and they seem to be working.
