更新NuGet时出现WebMatrix错误

Question

我有一个奇怪的问题已经有两天了。我使用的是WebMatrix 2(最新，已检查所有更新)。我运行NuGet来检查可用的更新。我看到了一些更新，除了NuGet.Core之外，所有的东西都得到了正确的更新。

我看到了最新的NuGet 2.2.0版本。我运行更新，它给我错误。表示找不到与NuGet.Core.2.2.0兼容的Microsoft.AspNet.WebPages.Administration版本。此错误的详细信息为：

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'.

什么意思？这是怎么回事。

Answer 1

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)，这不允许它更新到更高的版本。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。
