我正在使用红宝石 1.8.7。
当我用他在清单 5.1 中提供的代码更新 app/views/layouts/application.html.erb 时，static_pages/home 不再显示在服务器上。
原文：`
<!DOCTYPE html>
<html>
<head>
<title><%= full_title(yield(:title)) %></title>
<%= stylesheet_link_tag "application", :media => "all" %>
<%= javascript_include_tag "application" %>
<%= csrf_meta_tags %>
</head>
<body>
<%= yield %>
</body>
</html>
` 清单 5.1：
<!DOCTYPE html>
<html>
<head>
<title><%= full_title(yield(:title)) %></title>
<%= stylesheet_link_tag "application", media: "all" %>
<%= javascript_include_tag "application" %>
<%= csrf_meta_tags %>
<!--[if lt IE 9]>
<script src="http://html5shim.googlecode.com/svn/trunk/html5.js"></script>
<![endif]-->
</head>
<body>
<header class="navbar navbar-fixed-top navbar-inverse">
<div class="navbar-inner">
<div class="container">
<%= link_to "sample app", '#', id: "logo" %>
<nav>
<ul class="nav pull-right">
<li><%= link_to "Home", '#' %></li>
<li><%= link_to "Help", '#' %></li>
<li><%= link_to "Sign in", '#' %></li>
</ul>
</nav>
</div>
</div>
</header>
<div class="container">
<%= yield %>
</div>
</body>
</html>
我什至将 :media 和 :id 切换回 Ruby 1.8 风格的哈希。
我在服务器上遇到的错误：
