Sitecore-未定义根项目

我在尝试使用TDS部署时遇到以下错误。我不相信有任何自定义索引。我查看了以下链接并清除了\Data\index文件夹

什么会导致此错误

这也是我得到错误的url：

http:///sitecore

如果您浏览到此页面http://[yourhostname]/sitecore/admin/showconfig.aspx

搜索索引元素的任何实例，并检查此处的

路径

节点路径在内容树中实际存在

有关示例，请参见默认索引

更正任何无效的根值后，站点应再次工作。

问题原因 当Sitecore lucene索引已声明但其引用的

不在数据库中时，通常会出现此问题

注意：如果索引目标数据库是web，这可能是因为您尚未发布项目

问题修复 由于无法访问Sitecore桌面，您必须注释掉导致问题的索引。如果您不知道它是哪一个，您必须使用简单的旧尝试和错误，因为sitecore不会告诉您

要查看您在系统中声明的所有索引，请转到http://[yourhostname]/sitecore/admin/showconfig.aspx，然后搜索

Nice解释和解决方案。非常感谢。
