Ruby 轨道4。断点gem路径错误。要导入的文件找不到或不可读：断点

问题:

我有一个基本的Rails 4.0.10项目，我想在其中使用断点进行媒体查询

我的档案：

source 'https://rubygems.org'

gem 'rails', '4.0.10'

gem 'sqlite3'

gem 'httparty'

gem 'requirejs-rails'

gem "github_api"

gem "breakpoint", "~>2.4.0"

gem 'uglifier', '>= 1.3.0'

gem 'jquery-rails'

gem 'jbuilder', '~> 1.2'

group :doc do
  gem 'sdoc', require: false
end

当我在我的sass样式表中需要断点时，它会抛出：

Sass::SyntaxError in Stats#index
Showing /home/action/workspace/sofapp/sofa/app/views/layouts/application.html.erb where line #7 raised:

File to import not found or unreadable: breakpoint.
Load paths:

  /home/action/workspace/sofapp/sofa/app/assets/stylesheets

  (in /home/action/workspace/sofapp/sofa/app/assets/stylesheets/main.scss:5)

正如您从错误中看到的，Sass无法找到加载断点的正确路径。我查看了最后一个路径，发现目录/home/action/.rvm/gems/ruby-2.0.0-p247/gems/breakpoint-2.4.6/lib/stylesheets不存在，而是/home/action/.rvm/gems/ruby-2.0.0-p247/gems/breakpoint-2.4.6/stylesheets

问题:

我应该将资产管道配置为包含断点的正确路径，还是存在其他问题
