On my config/application.rb file I have:

require File.expand_path('../boot', __FILE__)

require 'rails/all'

Bundler.require(*Rails.groups)

module Evolution
  class Application < Rails::Application

    config.assets.initialize_on_precompile = false

  end
end

Any idea how to fix this error?

UPDATE #1

If I search for the word "bootstrap-theme" in the App directory, I find:

4 matches across 2 files:

/Users/andreucasadella/rails_projects/evolution/app/assets/stylesheets/bootstrap-theme.css:
  468            box-shadow: inset 0 1px 3px rgba(0, 0, 0, .05), 0 1px 0 rgba(255, 255, 255, .1);
  469  }
  470: /*# sourceMappingURL=bootstrap-theme.css.map */

And

/Users/andreucasadella/rails_projects/evolution/app/assets/stylesheets/bootstrap-theme.css.map:
    1: {"version":3,"sources":["less/theme.less","less/mixins/vendor-prefixes.less","bootstrap-theme.css","less/mixins/gradients.less","less/mixins/reset-filter.less"],"names":...

I understand that the "Unknown word" is on the file /bootstrap-theme.css.map and on line 1:14.

How do I identify space 14?

I have not been able to find an answer, therefore I decided to delete both map files: - bootstrap-theme.css.map - bootstrap.css.map

I will not be able live-edit my preprocessor source files in the DevTools Sources panel, but at least I can go on. Hope to find a better answer soon.

what are the .map files used for in Bootstrap 3.1?

I've solved problem for me. Bootstrap was installed by Bower in Rails app. I've removed bootstrap folder from vendor folder and run ```bower install```. Good Luck! :) – Pavel Kalashnikov Dec 16 '14 at 19:20
