两天以来我遇到了一个奇怪的问题。我正在使用 WebMatrix 2（最新，所有更新都已检查）。我运行 NuGet 来检查可用的更新。我看到了一些更新，一切都得到了正确更新，除了 NuGet.Core。

我看到最新的 NuGet 版本 2.2.0 可用。我运行更新，它给了我错误。说找不到与 NuGet.Core.2.2.0 兼容的 Microsoft.AspNet.WebPages.Administration 版本。此错误的详细信息是：

An error occurred.

Updating 'NuGet.Core 1.6.2' to 'Nuget.Core 2.2.0' failed. Unable to find a version of 'Microsoft.AspNet.WebPages.Administration' that is compatible with 'Nuget.Core 2.2.0'.

这是什么意思？这里有什么问题。

这是因为 http://nuget.org/packages/Microsoft.AspNet.WebPages.Administration包依赖于 nuget.core NuGet.Core (≥ 1.6.2 && < 1.7) 不允许它更新到更高版本。我看到这里已经提出了一个问题http://aspnetwebstack.codeplex.com/workitem/435使其与 2.x 版本兼容。
