Question

我正在关注Michael Hartl's book Ruby on Rails 3 Tutorail中的demo_app。该演示是一个简单的Scaffold用户名：string email：string

我的 application.html.erb 文件中出现错误：

Errno::EINVAL in Users#index 
Showing ~/demo_app/app/views/layouts/application.html.erb where line #6 raised: 
Invalid argument - cscript //E:jscript //Nologo //U /tmp/execjs20120323-4388-1an85xw-0.js 2>&1
(in ~/demo_app/app/assets/javascripts/users.js.coffee)

3: <head>
4:   <title>DemoApp</title>
5:   <%= stylesheet_link_tag    "application", :media => "all" %>
6:   <%= javascript_include_tag "application" %>
7:   <%= csrf_meta_tags %>
8: </head>
9: <body>

如果我将第6行打到：

<%= javascript_include_tag "default" %>

该程序将完美运行，但它不允许我删除用户（可能是因为它没有运行javascript）。

环境信息：

$ ruby -v
ruby 1.8.7 (2012-02-08 patchlevel 358) [i386-cygwin]

$ rails -v

Answer 1

尝试取消注释 gem'therubyracer'并运行捆绑，并且最好使用ruby的最后稳定版本

Answer 2

我在周围寻找讨论宝石温控器的其他问题。我找到了一个答案，表明了卡尔迪巴耶夫在这里所说的话。这对我不起作用。但是还有另一个建议要删除代码

//= require_tree .

来自app / assets / javascripts / application.js文件的

。

删除该代码使应用程序正常工作（包括销毁功能）。

Javascript不适用于javascrip_inlcue-tag Rails 3.2.2
