Error when compiling rails assets

I'm trying to compile my assets in order to put my project into production. When executing this command:

rake assets:precompile --trace RAILS_ENV=production

I get the following error:

** Invoke assets:precompile (first_time)
** Invoke assets:environment (first_time)
** Execute assets:environment
** Invoke environment (first_time)
** Execute environment
** Execute assets:precompile
rake aborted!

Tasks: TOP => assets:precompile

Whats happening? Am I compiling assets in the right way?

this my Javascript within the comments: 

// This is a manifest file that'll be compiled into application.js, which will include all the files
// listed below.
//
// Any JavaScript/Coffee file within this directory, lib/assets/javascripts, vendor/assets/javascripts,
// or any plugin's vendor/assets/javascripts directory can be referenced here using a relative path.
//
// It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the
// compiled file.
//
// Read Sprockets README (https://github.com/rails/sprockets#sprockets-directives) for details
// about supported directives.
//
//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require bootstrap-sprockets
//= require ckeditor/init
//= require_tree .

this is the error when open the page in the browser:

(index):21 GET http://dev.nutrimais.com.br/assets/application-c69ac193f2f610776253a81e6da332ce0bb1141cac0141b0d50c686d872126a5.css

Just discovered that if I use rake assets:precompile --trace it compiles. But using the rake assets:precompile --trace RAILS_ENV=production it gives me the errors

Put it in your gemfile:

 group :production do
      gem 'therubyracer'
    end

You have a bug in your Javascript within the comments function. Fix that and the app will compile! Im happy to take a look if you can post that function.
