1.gemFile

There's no grop after Rails 4, remember.

# group:assets Dogem ' sass-rails ', ' ~> 4.0.0 ' gem ' coffee-rails ', ' ~> 4.0.0 '    gem ' uglifier ', ' >= 1.3.0 ' # end# Page render gem ' jquery-rails '  #这个gem ' Execjs '      # Remember this gem ' Turbolinks '

2. Inconfig/application.rb Remember, application file, don't be right.

Config.assets.precompile << proc.new do |path|      If Path =~/\. (Css|js|scss|png|jpg|gif|json) \z/        full_path = Rails.application.assets.resolve (path). To_path        App_assets_ path1 = Rails.root.join (' app ', ' assets '). To_path        app_assets_path2 = Rails.root.join (' Public ', ' assets '). To_path        app_assets_path3 = Rails.root.join (' Vendor ', ' assets '). To_path        if Full_path.starts_with? app_assets_path1          true        else          if Full_path.starts_with? app_assets_path2            true          else            if Full_path.starts_ With? App_assets_path3              true            else              false            end    end End End

3. Tips config/environment/production.rb

   Config.action_controller.relative_url_root = '/discount_service '  #是用来 practical ah   Config.serve_static_assets = True   # Compress JavaScripts and CSS.  Config.assets.compress = True   config.assets.js_compressor =: uglifier   config.assets.css_compressor =: Sass

4. Finally, remember this.

Rails_env=production Rake Assets:precompile
