Rails coffeescript：TypeError：对象不支持此属性或方法

Question

我有以下rails配置：

Windows 7
Rails 4.1.1
Ruby 2.0.0p481
Gem: coffee-rails 4.0.1
Gem: coffee-script 2.3.0
Gem: coffee-script-source 1.9.1

TypeError: Object doesn't support this property or method
  (in c:/Users/mbratc01/Documents/Rails/manpower/app/assets/javascripts/welcome.js.coffee)

Extracted source (around line #9):
 7 <%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => false %>
 8 <%= javascript_include_tag 'jquery-1.11.1', 'data-turbolinks-track' => false %>
 9 <%= javascript_include_tag 'application', 'data-turbolinks-track' => false %>
10 <%= csrf_meta_tags %>
11 </head>

# Place all the behaviors and hooks related to the matching controller here.
# All this logic will automatically be available in application.js.
# You can use CoffeeScript in this file: http://coffeescript.org/

有没有人对是什么导致了这个错误有什么建议？

Answer 1

因此，CoffeeScript不能很好地使用Windows。您可能希望尝试降级CoffeeScript的版本，或者将其从GemFile中完全删除。

然后只需将.coffee文件重命名为一个简单的.js，并在Rails应用程序中创建常规javascript。
