我正在寻找在我的Rails 4项目中添加jquery并且我遇到路径问题。 在我的路径下面和我的application.js配置文件
~/git/myproject$rails console
Loading development environment (Rails 4.0.0)
irb(main):001:0> y Rails.application.config.assets.paths

应用
//= require jquery
//= require jquery_ujs
//= require dataTables/jquery.dataTables
看起来很好，但我无法在/ home / flex / git / myproject / app / assets / javascripts上加载js.coffee文件
如果我尝试添加//= require_tree .，则在加载页面时收到以下错误：
Sprockets::CircularDependencyError in Mycontrollers#index
与：
有关<%= javascript_include_tag "application", "data-turbolinks-track" => true %>
我不明白为什么jquery代码不起作用。怎么了？
在shops.js.coffee文件下面：
$(document).on 'page:load' ->
$('#shops').dataTable()
HTML输出下方：
