【问题描述】：
将我的 ruby on rails 应用程序上传到 heroku 会导致以下错误：
很抱歉，出了点问题。
这不会发生在我的本地机器上。
经过一些调试，我想我可能已经发现了错误，但不知道如何修复它。
在我的文件 application.html.erb 中，删除以下行解决了问题，但随后我的应用程序丢失了它的 jquery 移动主题。有什么想法可以解决这个问题吗？
导致问题的线路：
<%= javascript_include_tag "application" %>
application.html.erb 文件：
<!DOCTYPE html>
<html>
<head>
<title>Washapp</title>
<meta name="viewport" content="width=device-width">
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.0.1/jquery.mobile-1.0.1.min.css" />
<%= javascript_include_tag "application" %>
<script src="http://code.jquery.com/mobile/1.0.1/jquery.mobile-1.0.1.min.js"></script>
<%= csrf_meta_tags %>
<script>
if (window.location.hash == "#_=_")
window.location.hash = "";
</script>
</head>
<body>
<div data-role="page">
<%= yield %>
</div>
</body>
</html>

【问题讨论】：
-
您使用的是什么版本的导轨？可能与资产管道有关。根据您所处的环境，包含的资产会有所不同。guides.rubyonrails.org/asset_pipeline.html
-
我正在运行 Rails 3.2.2
-
是的，这与您的资产编译有关。阅读我发布的链接。
-
如果你不知道
heroku logs可能会有用 -
你的意思是 app/assets/javascripts/application.js？我刚刚用它更新了我的帖子
