【问题描述】：

我正在为我的应用程序设置新的登台服务器。现有的暂存环境以及具有相同发行版本的开发环境都可以正常工作。

尝试cap deploy，我收到以下错误：

    [1906b0ea] Command: cd /home/user/appname/releases/20160831113756 && ( export RAILS_ENV="production" ; ~/.rvm/bin/rvm 2.3.0 do bundle exec rake assets:precompile )
rake aborted!

这是我的application.js 文件 //

= require jquery
            //= require jquery_ujs
            //= require datatables
            //= require turbolinks
            //= require cocoon
            //= require select2
            //= require highcharts
            //= require highcharts/highcharts-more
            //= require sparklines
            //= require rangeslider.js/dist/rangeslider
            //= require Sortable
            //= require moment
            //= require pikaday
            //= require tooltipster
            //= require urijs
            //= require jscolor/jscolor
            //= require_tree .

这里是Gemfile.lock的部分内容

    jquery-datatables-rails (3.3.0)
      actionpack (>= 3.1)
      jquery-rails
      railties (>= 3.1)
      sass-rails
   ....
       ajax-datatables-rails (0.3.1)
      railties (>=

3.1)

我搜索了几个 SO 问题，但似乎没有一个是相关的。

您对可能导致该问题的原因以及如何解决它有任何想法吗？

【解决方案1】：

我发现您正在使用jquery-datatables-rails gem。

我查看了那个gem的README，安装说明说正确的引用方法如下：

# app/assets/javascripts/application.js
//= require dataTables/jquery.dataTables
