Ruby on Rails中的隨機jQuery數據表路由問題

Question

因此，我在Ruby on Rails應用程序中使用了數據表，最近我剛剛開始隨機獲取此錯誤消息，但我不確定為什么。

這是消息：

這是我的application.js和application.css文件的樣子：

#application.js
/ 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 vendor/assets/javascripts of plugins, if any, 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/sstephenson/sprockets#sprockets-directives) for details
// about supported directives.
//
//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require_tree .
//= require bootstrap
//= require dataTables/jquery.dataTables
//= require dataTables/bootstrap/3/jquery.dataTables.bootstrap

。

#application.css
/*
 * This is a manifest file that'll be compiled into application.css, which will include all the files
 * listed below.
 *
 * Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets,
 * or vendor/assets/stylesheets of plugins, if any, can be referenced here using a relative path.
 *
 * You're free to add application-wide styles to this file and they'll appear at the bottom of the
 * compiled file so the styles you add here take precedence over styles defined in any styles
 * defined in the other CSS/SCSS files in this directory. It is generally better to create a new
 * file per style scope.
 *
 *= require_tree .
 *= require_self
 *= require dataTables/jquery.dataTables
 */

知道我為什么要得到這個嗎？ 實際的文件在那里（我只是手動放置了它們，但是我不確定這里還缺少什么。

Answer 1

將行放在application.js中的需求樹之前

//= require bootstrap
//= require dataTables/jquery.dataTables
//= require dataTables/bootstrap/3/jquery.dataTables.bootstrap

Answer 2

在CSS清單中，將*= require dataTables/jquery.dataTables *= require_tree .之前*= require_tree .
