所以我接受缓存或其他东西在我身上发生了一些奇怪的事情。显然已经清空了缓存，删除了包文件夹并重新获得了包。
https://www.nuget.org/packages/Google.ProtocolBuffers/
重命名了 nupkg zip，查看并找到了 dll。他们只是没有提取 - 这表示 nuspec 对于其中的文件夹结构看起来是错误的。但是很难相信只有我有这个问题。
我以前从未有过这种行为，并且已经沉没了大约 2 个小时。所以希望有人能指出非常明显的问题并解释为什么我过去使用的一个包突然变得很糟糕。
编辑以获取更多信息：我在 vs2015 企业版中使用 4.6.1 控制台项目进行了复制（只是标准的 .net，而不是 dnx 或任何时髦的东西）。刚用 4.5.2 试过，我也有同样的问题。没有引用被添加到项目中的任何 dll。此外，在包文件夹中没有 dll - xml 文件虽然完成了它。但是，如果我进入 nupkg，重命名为 .zip 并打开，我可以看到它们应该在的 dll。我通常也以管理员身份运行 vs - 软件包安装也从命令行失败（并不是我期望有任何不同）
额外编辑：其他 nuget 包也在工作。我正在推进其他领域，这些领域也很重。只是这一个包给我带来了问题。
