Installing using LESS

Installing the Gem

The Twitter Bootstrap Rails gem can provide the Bootstrap stylesheets in two ways.

The plain CSS way is how Bootstrap is provided on the official website.

The Less way provides more customization options, like changing theme colors, and provides useful Less mixins for your code, but requires the Less gem.

Installing the Less stylesheets

To use Less stylesheets, you'll need the less-rails gem.

Include these lines in the Gemfile to install the gems from RubyGems.org:

gem "less-rails" #Sprockets (what Rails 3.1 uses for its asset pipeline) supports LESS
gem "twitter-bootstrap-rails"

Then run bundle install from the command line:

bundle install

Then run the bootstrap generator to add Bootstrap includes into your assets:

rails generate bootstrap:install less

If you need to skip coffeescript replacement into app generators, use:

rails generate bootstrap:install less --no-coffeescript
