【问题描述】:
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脚手架用户名:字符串电子邮件:字符串
我的 application.html.erb 文件出现错误:
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 行更改为:
<%= 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]

【问题讨论】:
-
发布您的
users.js.coffee文件。 -
能否把app/assets/javascripts/users.js.coffee的内容贴出来。还要确保您遵循 Rails 3.2 的本书版本 - ruby.railstutorial.org/ruby-on-rails-tutorial-book?version=3.2
-
john,确认我正在关注 version=3.2。
-
上面发布的 user.js.coffee 的内容。
-
请发布您的 application.js 和您的 app/assets/javascript 文件夹中的文件。
