Ошибка: файл для импорта не найден или нечитабельно: bootstrap-sprockets

Question

Я использую рельсы 5, и по какой-то причине я получаю сообщение об ошибке, хотя я ничего не менял. Я попытался изменить окончание имени файла и изменить номер версии gem bootstrap-sass, но ничего не работает.

Как я могу решить эту ошибку?

Это следующее сообщение об ошибке:

application.scss

@import "bootstrap-sprockets"; 
@import "bootstrap"; 

... 
all the styles 

application.css

/*

Вы пробовали предложения here: В том числе это

gem 'bootstrap-sass', '~> 3.3.7' 
gem 'sass-rails', '>= 3.2' 

в вашем Gemfile, делая расслоение установки, а затем перезапустить сервер.

И пытается информация в docs В частности, где он говорит:

Then, remove all the *= require_self and *= require_tree . statements from the sass file. Instead, use @import to import Sass files. 

Do not use *= require in Sass or your other stylesheets will not be able to access the Bootstrap mixins or variables. 

Require Bootstrap Javascripts in app/assets/javascripts/application.js: 

//= require jquery 
//= require bootstrap-sprockets 
bootstrap-sprockets and bootstrap should not both be included in application.js. 

bootstrap-sprockets provides individual Bootstrap Javascript files (alert.js or dropdown.js, for example), while bootstrap provides a concatenated file containing all Bootstrap Javascripts.
