添加设计gem后登录页面出错

Question

我正在使用一个曾经完美工作的应用程序在我的本地工作。 但是现在，当连接到我的localhost时，我收到此消息错误。 我使用了devise-2.2.3 gem

Started GET "/users/sign_in" for 127.0.0.1 at 2013-08-12 16:54:42 +0200
Creating scope :closed. Overwriting existing method MergeRequest.closed.
Processing by Devise::SessionsController#new as HTML
  Rendered devise/sessions/new.html.haml within layouts/devise (1.8ms)
  Rendered layouts/_head.html.haml (26.1ms)
Completed 500 Internal Server Error in 59ms

我注意到没有layouts/_head.html.haml 。 那么有人知道这种错误的起源吗？

正如所建议的那样，我发布完整的堆栈，虽然我认为它没有我之前发布的信息量多;）

好吧，布局不是你的问题（我不认为），当在堆栈溢出上发布错误时，发布堆栈跟踪非常重要。

堆栈跟踪是拥有关于错误的所有知识的圣杯，没有它，我们就完全迷失了。 发布堆栈跟踪，并尝试重新启动rails服务器。 确保迁移数据库，然后我们可以修复错误。

这一行：

= javascript_include_tag "application", "internationalization.js", "http://ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"

被打破。

我不知道为什么，可能是因为你在同一行列出了JS文件。 javascript文件本身可能存在问题，但不确定，但这就是错误所在。
