@ryana what do I do with sprockets-patch.rb - do I need to place it somewhere or run it?

@pwgustafson you place it in config/initializers/ -- the files in that directory get executed in alphabetical order when the Rails environment boots. Sorry for the late response. I didn't get a notification of this comment.

sprockets 4.0 is under active development. Maybe it's time for a new PR there
