我尝试使用此命令卸载重新安装：
Uninstall-Package MvcScaffolding -RemoveDependencies
答案 0 :(得分：2)
我也遇到了这个错误的问题。对我来说有用的是在每次卸载时使用单独的命令卸载MvcScaffolding及其每个依赖项，如“卸载 - 软件包T4Scaffolding＆＃39;”。我还从驱动器和源代码控制中删除了相关的文件和文件夹。然后，我重新安装，一切都很好。删除文件似乎很关键。

正如对原始问题的评论所述，我认为这是MVC脚手架中的一个错误，请参阅：http://mvcscaffolding.codeplex.com/workitem/27
