成功安装后，Nuget Install总是失败

我正在使用Umbraco 7.3.1，Ucommerce 6.8.3，NuGet 3.2.6并在Windows 10 pro（x64）上运行Visual Studio 2015的项目中

由于某种原因，我无法在项目中安装任何Nuget软件包。在项目中安装ucommerce之后，似乎会出现此问题。

这是我尝试安装jQuery的示例。请注意，此问题与jQuery无关，所有软件包都收到此错误。

奇怪的是，如果首先说成功将'jQuery 2.1.4'成功安装到[Project-Name]，然后立即安装失败。滚回来...

我似乎从来没有得到任何有用的堆栈跟踪。

我最初创建此项目的一位同事也遇到了同样的问题。

我们尝试了很多事情，包括干净地重新安装Windows，并使用新的解决方案文件和新的数据库从头开始重新设置整个项目，但是问题总是会再次出现。

编辑2：我尝试将NuGet从3.2.6降级到3.0.6，但没有任何变化。

编辑3：安装VS2013，并尝试使用NuGet 2.8，但我仍然遇到相同的问题

编辑4：尝试在错误发生后在Package Manager控制台中运行以下命令。这是VS2013 / NuGet 2.9的结果

$error[0].Exception.StackTrace

从VS2015 / NuGet 3.2起，$ error [0] .Exception.StackTrace没有结果。
