Как использовать компас в Laravel?

С laravel-elixir-compass (а также gulpfile.js от README.md) это говорит:

$ gulp
module.js:340
throw err;
^

Error: Cannot find module 'laravel-elixir/ingredients/helpers/utilities'
at Function.Module._resolveFilename (module.js:338:15)

Итак, я пришел к выводу, что это опирается на elixir <= 0.9.1, поскольку этот когда файл был переименован. А также этот это ближайший коммит с ударной версией, которую я смог найти.

Затем я заметил предупреждение «Проект перемещен» в README.md,

С laravel-elixir-sass-compass (а также gulpfile.js от README.md):

С любым пройденным путем (mix.compass('app.sass')):

$ gulp

Run "compass -h" to get help.
