如何获取Twitter的引导的减档与西纳特拉AssetPack工作？(How do I get Tw

我想获得引导的减档与工作西纳特拉AssetPack ，但我正在逐渐减分析器错误。这些错误导致我相信，通过bootstrap.less要导入的文件少不知道对方。

我有一个app.rb文件：

require 'sinatra/base'
require 'sinatra/assetpack'

class App < Sinatra::Base
  set :root, File.dirname(__FILE__)
  register Sinatra::AssetPack

  assets do
    css :bootstrap, [
      '/css/bootstrap.css'
    ]

  end

  get '/' do
    erb :index
  end

  # start the server if ruby file executed directly
  run! if app_file == $0
end

我复制了所有的引导少的文件到/app/css目录，使每个@import声明中的CSS，而不是结束.LESS修改bootstrap.less（实际的文件扩展名并没有改变，虽然）。我也把一切了Github上： https://github.com/elevine/sinatra-assetpack-bootstrap

下面是我得到的错误之一的堆栈跟踪的前半部分：

.tab-focus在mixins.less限定，并且该错误由reset.less这在bootstrap.less第一进口起源。我试图重新安排进口秩序，但它并没有解决问题。

是否有可能获得bootstrap.less的@import声明了在此设置正常工作？

Answer 1:

还有的是一堆的AssetPack创业板工作的近期（以较少的支持现已内置）。如果更新至最新的宝石，它是很容易获得较少的工作。这吉斯特有一个完整的例子： https://gist.github.com/4652773 。

Answer 2:

我找到了最好的解决办法是简单的路径少的文件添加到Less.path阵列。有没有必要改变任何原始文件少的。

例如：

require 'sinatra/base'
require 'sinatra/assetpack'

class App < Sinatra::Base
  set :root, File.dirname(__FILE__)
  Less.paths <<  "#{App.root}/app/css" 

  register Sinatra::AssetPack

  assets do
    css :bootstrap, [
      '/css/bootstrap.css'
    ]

  end

  get '/' do
    erb :index
  end

  # start the server if ruby file executed directly
  run! if app_file == $0
end
