所以我接受一些奇怪的事情发生在我的最后用缓存或其他东西。显然已经清空了缓存，删除了包文件夹和regot包。
https://www.nuget.org/packages/Google.ProtocolBuffers/
重新命名nupkg zip，查看并且dll在那里。它们只是被提取出来 - 说nuspec看起来对它的文件夹结构是错误的。但很难相信它只是我有这个问题。
我之前从未有过这种行为，并且已经沉入了大约2个小时。所以希望有人可以指出真正明显的，并解释为什么我过去使用过的包装突然变得笨拙。
编辑以获取更多信息： 我在vs2015企业中使用了4.6.1控制台项目（只是标准的.net而不是dnx或任何时髦的东西）。 刚试过4.5.2，我有同样的问题。没有引用添加到项目中的任何dll。而且在packages文件夹中没有dll - 尽管xml文件已经完成了。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是的dll。我也经常运行vs作为管理员 - 包安装也从命令行失败（不是我预期的任何不同）
额外编辑： 其他nuget包正在运行。我正在进步的区域，也是包装重。它只是这一个包给我的问题。

答案 0 :(得分：1)
结果我做了两件事
1）转到%userprofile%\.nuget并删除包文件夹（但请记住，我已经完成了这个并且没有单独修复它）。我注意到这里的版本反映了我遇到的问题 - 而且我以前删除了这个，我知道简单地删除这个文件夹是不够的。
2）在管理模式vs dev命令提示符“devenv /resetuserdata”
新的解决方案4.5.2，控制台和第一次工作。
是什么造成的？ 不是最模糊的。
