How to resolve Sprockets::DoubleLinkError

For me, this simply occurred because I had two style sheets where I should have had only one. In my case, I had

myapp/app/assets/stylesheets.application.css

AND

myapp/app/assets/stylesheets.application.css.scss

where I should have had just one of those

I removed application.css and the problem went away
