Question

我遇到了一个问题，我无法安装任何NugetPackages。这包括更新现有的软件包，它将删除旧软件包并且无法安装更新的软件包，使我的解决方案处于破碎状态！

以下是尝试安装SpecFlow时Package Manager控制台输出的示例：

正如您所看到的，它会下载软件包（我可以看到它出现在packages文件夹中的文件系统中），但它无法安装并从磁盘中删除它。我已经搜索并验证了包文件夹没有意外地签入源控件。这是在我使用Visual Studio 2015打开的任何解决方案上发生的。我尝试过控制台和包管理器GUI，但都失败了。

事情似乎在VS2013中起作用（这是我一直使用的解决方法之一，但不是长期解决方案）。

VS 2015与Nuget完全一致。

无法使用VS2015安装/更新任何nuget软件包
