title: Warning using twitter-bootstrap-rails generators on Windows
body: <p>I'm trying to use the twitter-bootstrap-rails gem on my first Rails project, on a Windows 7 machine running </p>
  
  <pre><code>ruby 1.9.3p125 (2012-02-16) [i386-mingw32]
  Rails 3.2.1
  twitter-bootstrap-rails 2.1.1
  </code></pre>
  
  <p>When I run <code>rails g bootstrap:install</code> I get the following:</p>
  
  <pre><code>[WARNING] Please install gem 'therubyracer' to use Less.

  <p>Here's my Gemfile:</p>
  
  <pre><code>source 'https://rubygems.org'
  gem 'rails', '3.2.1'
  gem 'pg'
  
  group :assets do
    gem 'sass-rails',   '~&gt; 3.2.3'
    gem 'coffee-rails', '~&gt; 3.2.1'
    gem 'twitter-bootstrap-rails', :git =&gt; 'git://github.com/seyhunak/twitter-bootstrap-rails.git'
    gem 'uglifier', '&gt;= 1.0.3'
  end
  
  gem 'jquery-rails'
  </code></pre>
  
  <p>I've tried including <code>gem therubyracer</code> in my Gemfile, but I get compilation errors about the libv8 gem, which <a href="https://stackoverflow.com/questions/6356450/therubyracer-gem-on-windows">isn't available on Windows</a>. I've also tried <code>gem therubyracer, :platform =&gt; :ruby</code>, but Bundler still attempts to install therubyracer on <code>bundle install</code>. I also tried installing node.js and including <code>gem execjs</code>, but to no avail.</p>
  
  <p>Every solution I come across doesn't seem to help at all. I'd like to use LESS rather than static CSS on this project, so a solution to allow me to use LESS with Rails on a Windows machine would be most helpful.</p>
