все дороги указывают на начальную загрузку

Реферальная цепочка:

Railscast-328 (основы начальной загрузки Twitter) относится кhttp://www.sitepoint.com/twitter-bootstrap-less-and-sass-understanding-your-options-for-rails-3-1/ что относится кhttps://github.com/jlong/sass-bootstrap который, в свою очередь, заявляет, что есть новый официальный порт начальной загрузки дляhttps://github.com/twbs/bootstrap-sass что является еще одним из вариантов в статье Twitter-начальной загрузки

Сообщается, что проблема с самоцветом bootstrap-rails:https://github.com/anjlab/bootstrap-rails/issues/91

Я считаю, что установил правильно

Драгоценные камни

gem 'sass-rails', '>= 3.2' # sass-rails needs to be higher than 3.2
gem 'bootstrap-sass', '~> 3.1.1'

устанавливаются (пробуются снаружи и внутри группы активов), application.css.scss содержит

@import "bootstrap";

только.

но это дает мне ошибку

При попыткеbundle exec rake assets:precompile это дает эту ошибку:

rake aborted!
Undefined variable: "$alert-padding".
