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:

<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:
