我有一个小的应用程序，在本地工作正常，但部署到AppHarbor时会产生标题中显示的错误..我记得当我第一次安装JqueryUi时在本地遇到一些麻烦，但我认为在我重新启动Visual Studio后解决了或类似的东西..你们中的任何人可能有类似的问题吗？
我在web.config中添加了命名空间：
<namespaces>
<add namespace="JQueryUIHelpers" />
<add namespace="System.Web.Mvc" />
<add namespace="System.Web.Mvc.Ajax" />
<add namespace="System.Web.Mvc.Html" />.....
这是编译器输出：
