Question

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。我看到一些更新，一切都得到了正确的更新，除了NuGet.Core。

我看到最新的NuGet 2.2.0版本可用。我运行更新，它给了我错误。说无法找到与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？这里有什么不对。

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＆amp;＆amp;＆lt; 1.7），这将不允许它将其更新为更高版本。我发现http://aspnetwebstack.codeplex.com/workitem/435已经存在一个问题，因为它与2.x版本兼容。
