上限部署资产预编译错误

Question

我正在为我的应用程序设置新的登台服务器。 现有的暂存以及具有相同发行版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!
...
Sprockets::FileNotFound: couldn't find file 'datatables' with type 'application/javascript'
Checked in these paths:

      /home/user/ap

pname / releases / 20160831113756 / vendor / assets / bower_components

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 .

这是Gemfile.lock

    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）

我已经搜索了几个SO问题，但是似乎都没有问题。

您有什么想法可能导致这种情况以及如何解决？

Answer 1

我看到您正在使用jquery-datatables-rails gem。

我查看了该gem的自述文件 ，安装说明说了引用它的正确方法，如下所示：

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