Rails 3.2.12 with less and Twitter Bootstrap: V8 Error

Question

I would like to use Twitter Bootstrap with a current Ruby on Rails version. I tried to use "less-rails-bootstrap". I followed: http://rubysource.com/twitter-bootstrap-less-and-sass-understanding-your-options-for-rails-3-1/

I created a new rails project. Then I added "gem 'less-rails-bootstrap'" to the Gemfile, installed it and after that I added " *= require twitter/bootstrap" to application.css

I got this error:

Showing /var/www/lrb/app/views/layouts/application.html.erb where line #5 raised:

V8::Error
(in /usr/lib/ruby/gems/1.8/gems/less-rails-bootstrap-2.3.0/vendor/assets/stylesheets/twitter/bootstrap.css.less)

I could not find how I can fix the V8::Error. Line 5 in application.html.erb: <%= stylesheet_link_tag "application", :media => "all" %>

My installed Gem's:

I use 'bootstrap-sass' gem but I suppose it follows the same convention.

After I bundled the gem, I do not add anything in the application.css; according with the documentation of the gem:

We recommend against using //= require directives, since none of your other stylesheets will be able to use the awesome mixins that Bootstrap has defined

Instead you can create a new css.scss file and at the top @import 'bootstrap';

Job done!
