NuGet: jQuery Mobile install error

Question

I created an empty MVC 2 Empty Web Application, then use NuGet to upgrade my project to MVC 4. After that I use NuGet to install jQuery Mobile, but get errors. Here is the whole error messages

I am using Visual Studio 2010. I have found this link closed to my situation and tried it but still get the error messages. Any help will be appreciated.
