If it helps, it looks like sass-rails did the transition here.

Possible duplicate of PR #106?

imechemi commented 8 years ago

FYI, this happened to me when I quit terminal without shutting down the server and when I opened my terminal again and start my server, I saw this errors in stack trace. I used to kill the server process when I forget to quit the server, but now for this error I can't even find the process tied to the rails server.

I'm still getting this error, even with less-rails 2.7.0:
