在rails 3.2.16上生成第一个状态

Question

当生成我的第一个状态时，即当我执行localhost / status时，我有以下错误：

ExecJS::RuntimeError in Statuses#index

Showing C:/Users/NEBELYN/ruby1/gopbook/app/views/layouts/application.html.erb where line #6 raised:

(in C:/Users/NEBELYN/ruby1/gopbook/app/assets/javascripts/statuses.js.coffee) 
Extracted source (around line #6):

3: 
4: Gopbook 
5: <%= stylesheet_link_tag "application", :media => "all" %> 
6: <%= javascript_include_tag "application" %> 
7: <%= csrf_meta_tags %> 
8: 
9: Rails.root: C:/Users/NEBELYN/ruby1/gopbook

这是我的创业板文件
