【问题描述】：
我无法在我们的一种解决方案上安装/升级/卸载任何 nuget 包。据我所知，这与 PCL 无关，因为它在两台机器上是相同的。解决方案中的三个项目之一可以使用 nuget 进行更新，另外两个（较大的项目）失败并出现下面的堆栈跟踪。
有没有人看到这个或知道如何解决它？我们在 packages.config 中没有重复的包名称，清除它们、文件夹和引用没有帮助，我们在管理员模式下运行并更新它。
虽然类似于这些 [1]、[2] 和 [3]，但堆栈跟踪不匹配，并且没有任何修复工作。
[1]Visual Studio 2015, Nuget and “same key has already been added.”
[2]An item with the same key has already been added while Installing nuget package
[3]installing nuget package "same key has already been added."

进一步挖掘，我发现这也会导致问题（我怀疑这是运行的底层命令）
