使用InfoPath表单部署SharePoint 2010解决方案时出错（路径不是合法表单。）

我是SharePoint和.Net开发的新手，若我的问题答案显而易见，那个么很抱歉

我已经创建了SharePoint解决方案，它使用InfoPath表单。当我从Visual Studio部署它时，一切正常，但当我尝试从web界面部署WSP包时，它失败并出现错误：

Microsoft.SharePoint.c__DisplayClass1.，这说明发生错误，然后路径属性不正确，但我无法理解当前的目录以及如何更改路径属性。你能帮帮我吗

提前谢谢你。
我找到答案了。现在它起作用了。问题的根源似乎是：
我尝试将WSP场解决方案添加到沙盒解决方案库中。我必须使用另一种方式进行部署，例如PowerShell

PS：谢谢你
