我一直在关注Michael Hartl出色的RoR教程,但我正在使用RoR 3.1.我是RoR 3.1的新手,需要有关资产管道的帮助.这是我的问题:
在继续讨论第5.3节之前,我想我想推进Heroku,看看事情是如何发展的.令我惊讶的是"GET /"导致错误500.在我的本地开发环境中一切都很好.然后我尝试在production-environment(rails s -e production)下运行我的本地sample_app .相同的结果,错误500:
Sprockets::Helpers::RailsHelper::AssetPaths::AssetNotPrecompiledError in Pages#home
Showing /Users/john/Projects/sample_app/app/views/layouts/_stylesheets.html.erb where line #4 raised:
blueprint/screen.css isn't precompiled
支持信息:
我按照Michael的第13.1.4节建议进行操作,并将以下内容作为我的app/views/layouts/application.html.erb:
<!DOCTYPE html>
<html>
<head>
<title><%= title %></title>
<%= render 'layouts/stylesheets' %>
<%= stylesheet_link_tag "application" %>
<%= javascript_include_tag "application" %>
<%= csrf_meta_tags %>
</head>
<body>
<div class="container">
<%= render 'layouts/header' %>
<section class="round">
<%= yield %>
</section>
<%= render 'layouts/footer' %>
</div>
</body>
</html>
app/views/layouts/_stylesheets.html.erb的内容:
<!--[if lt IE 9]>
<script src="http://html5shiv.googlecode.com/svn/trunk/html5.js"></script>
<![endif]-->
<%= …我试图预编译资产(rake assets:precompile或bundle exec rake assets:precompile),但我总是得到错误

有谁知道什么可能是错的？
