警告在Windows上使用twitter-bootstrap-rails生成器

Question

我正在尝试在运行的Windows 7计算机上的第一个Rails项目中使用twitter-bootstrap-rails gem

ruby 1.9.3p125 (2012-02-16) [i386-mingw32]
Rails 3.2.1
twitter-bootstrap-rails 2.1.1

当我跑步时,rails g bootstrap:install我得到以下内容:

[WARNING] Please install gem 'therubyracer' to use Less.
    C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/bundler-1.1.5/lib/bundler/runtime.rb:74:in `require': cannot load such file -- twitter/bootstrap/rails (LoadError)
        from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/bundler-.1.5/lib/bundler/runtime.rb:74:in 'rescue in block in require'
        from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/bundler-.1.5/lib/bundler/runtime.rb:62:in 'block in require'
        from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/bundler-.1.5/lib/bundler/runtime.rb:55:in 'each'
        from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/bundler-.1.5/lib/bundler/runtime.rb:55:in 'require'
        from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/bundler-.1.5/lib/bundler.rb:119:in `require'

        from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/railties-3.2.1/lib/rails/commands.rb:24:in `<top (required)>'
        from script/rails:6:in `require'
        from script/rails:6:in `<main>'

这是我的Gemfile:

source 'https://rubygems.org'
gem 'rails', '3.2.1'
gem 'pg'

group :assets do
  gem 'sass-rails',   '~> 3.2.3'
  gem 'coffee-rails', '~> 3.2.1'
  gem 'twitter-bootstrap-rails', :git => 'git://github.com/seyhunak/twitter-bootstrap-rails.git'
  gem 'uglifier', '>= 1.0.3'
end

gem 'jquery-rails'

我试过gem therubyracer在我的Gemfile中加入,但是我得到了关于libv8 gem的编译错误,这在Windows上是不可用的.我也尝试过gem therubyracer, :platform => :ruby,但Bundler仍然试图安装therubyracer bundle install.我也尝试过安装node.js和包括gem execjs但无济于事.

我遇到的每一个解决方案似乎都没有帮助.我想在这个项目中使用LESS而不是静态CSS,因此允许我在Windows机器上使用LESS和Rails的解决方案将是最有帮助的.

Answer 1

我已经切换到使用bootstrap-sass gem.

因此,我可以使用SASS作为CSS预处理器,而不是使用LESS.缺点是它似乎没有任何代码生成器.
