我尝试使用以下命令卸载重新安装：

Uninstall-Package MvcScaffolding -RemoveDependencies

我也遇到了这个错误的问题。对我有用的是卸载 MvcScaffolding 及其每个依赖项，每次卸载都有一个单独的命令，如“Uninstall-Package T4Scaffolding”。我还从我的驱动器和源代码管理中删除了它们相关的文件和文件夹。然后，我重新安装，一切都很好。删除文件似乎是关键。

正如对原始问题的评论中提到的，我相信这是 MVC 脚手架中的一个错误，请参阅： http: //mvcscaffolding.codeplex.com/workitem/27
