【问题描述】：

所以我按照说明 here 开始使用 vNext。

一切顺利，直到我进入必须运行kpm restore 的步骤，并且我在控制台窗口中得到以下输出：

有人对此有解决方案吗？

【解决方案1】：

看看 fiddler 发生了什么。我可以看到它正在尝试从我的私人提要中恢复软件包。我的私人提要返回 404 页，导致它失败。

解决方案是打开 Visual Studio 并转到工具 > 库包管理器 > 包管理器设置... > 包源。然后我不得不取消选择除 nuget.org 之外的所有源并添加 https://www.myget.org/F/aspnetvnext/ 作为包源。

保存后我再次尝试，一切正常

【讨论】：

如果 jaywayco 回答不起作用，请尝试在创建新项目时将 .NET Framework 版本设置为 4.5.3。像 4.5.1 这样的低版本应该可以工作，但我没有测试它们。
对于 VS2013，它是工具 > NuGet 包管理器 > 包管理器设置 > 包源。这适用于您没有 VS2015 预览版并且您只是使用命令行或 PowerShell 的情况。
感激不尽！花了几个小时试图解决这个问题......除了我的机器上安装了 PostSharp 对我来说也是一样的，所以我只需要从包资源列表中取消选择它，一切都很好。
