Ruby on rails Rails-客户端验证不'；我不能在AmazonEC2上工作

我正在使用gem，这是我在Gemfile中的内容：

#gem "client_side_validations", "~> 3.2.6"
gem 'client_side_validations', git: 'https://github.com/bcardarella/client_side_validations.git', branch: '3-1-stable' # working well on localhost as the line above

Capistrano gem用于部署到Amazon EC2，但当我部署代码并检查网站时，我在日志中看到以下错误：

ActionView::Template::Error (couldn't find file 'rails.validations'
  (in /home/deployer/xxx/releases/20130922134530/app/assets/javascripts/application.js:16)):
    3:     %title xxx
    4:     %meta{:name => "msvalidate.01", :content => "70FDF21E6271BE469BC86873DE55F921"}
    5:     = stylesheet_link_tag    "application", :media => "all"
    6:     = javascript_include_tag "application"
    7:     = filepicker_js_include_tag
    8:     %link{:href => 'http://fonts.googleapis.com/css?family=Lato:100,300,400,700,900,100italic,300italic,400italic,700italic,900italic', :rel => 'stylesheet', :type => 'text/css'}
    9:     :javascript
  app/views/layouts/application.html.haml:6:in `_app_views_layouts_application_html_haml___4198895688777468705_70291650639660'

在EC2上安装这个gem似乎有一些问题。我在Heroku上的几个项目中使用了这个gem，一切都很好，但我无法让它在AmazonEC2上工作

有什么我遗漏的或是什么吗

谢谢

您是否在本地主机或生产环境上预编译了这些资产？不确定该如何正确执行。请在服务器上运行rake assets:precompile
