安装Juice软件包中的Erorr

Question

我想安装Juice，但我面临着复杂的问题。我的操作系统是“Windows 7终极版”，我使用Visual 2012与NuGet软件包管理器2.0.30625.9003和dotNetFrame Work4.5，无论如何，我尝试了Tools>Extension、更新和命令提示符(PM> install )来安装果汁，但在这两种情况下，我都得到了这样的错误：

**PM> Install-Package JuiceUI

Attempting to resolve dependency 'jQuery.UI.Combined (≥ 1.9.0)'.

我想知道是否有人能帮我解决这个问题！我想它需要DotNetframeWork 3.5，但正如你所知，3.5并不适用于Windows7，而Juice工作在visual 2010及以后。所以我完全搞混了，我该怎么办！？

Answer 1

错误信息本身就解释了这个问题-

安装-软件包:无法安装软件包'JuiceUI 1.1.1‘。您正在尝试将此包安装到目标为'.NETFramework，Version=v3.5'的项目中。

juiceUI不工作在4.0以下。更改项目设置以使用.Net 4.0
