Can you try my fork and see if it fixes your problem? https://github.com/brendon/less-rails/tree/fix-sprockets-loading

Hi! I have the same issue.
@brendon I just checked your branch - it works.

Great to hear @PlugIN73 :) I'm having trouble getting the test suite to run with 4 beta but I think it's more about the manifest.js file not being read in order for the tests to find the assets. I've opened an issue here: rails/sprockets#484
