ruby-on-rails - TypeError:对象不支持此属性或方法

我已经创建了rails应用程序，在那里我创建了一个数据库（空）。当我试图查看我的产品页面时，我在http://localhost:3000/products页面上收到以下错误。在迁移数据库之前，应用程序运行正常。我正在使用Therubyracer并在Windows7上运行。

ExecJS::ProgramError in Products#index
Showing C:/RailsInstaller/DevKit/home/JP/nameofapp/app/views/layouts/application.html.erb where line #16 raised:

TypeError: Object doesn't support this property or method
  (in C:/RailsInstaller/Ruby2.1.0/lib/ruby/gems/2.1.0/gems/turbolinks-2.5.3/lib/assets/javascripts/turbolinks.js.coffee)
Extracted source (around line #16):

17     <%= csrf_meta_tags %>

这是我在rails服务器上得到的：

谢谢你的帮助。

最佳答案

我从application.js中删除了require_树，它成功了

//= require jquery
//= require jquery_ujs
//= require turbolinks
// require_tree .
