undefined method `empty?' for #<ActionDispatch::Response

[aesnyder]

When running rake cucumber DEADWEIGHT=true I get the following error undefined method empty?' for #<ActionDispatch::Response`

Any suggestions?

Sorry, I'm afraid I don't maintain this project any more - I haven't used it in years.

I recommend you try another tool - a quick Google turns up PurifyCSS and UnCSS. I'll update the README accordingly.
