dotnet cli - "检测到包降级"

Question

dotnet restore在完成清除所有nuget缓存,dnx缓存和cli使用beta通道更新的过程后,我终于设法获得了一个项目的依赖项下载.

但使用project.json下面的内容,我得到一个错误;

警告:检测到的软件包降级:Microsoft.Dnx.Compilation.CSharp.Abstractions从1.0.0-rc2-16553到1.0.0-rc2-16552

我不确定这意味着什么,或者如何解决它.事情仍然下载,但这关心我.

我使用以下内容;

DOTNET/CLI

其中一个库明确需要 1.0.0-rc2-16552 版本，这就是您收到警告的原因。一旦库 u[升级到支持更高版本，警告就会消失。这是一篇旧帖子，因此不确定在您发帖时哪个库正在执行此操作，但对于有相同警告的人，请浏览您的库并查看哪个库具有版本依赖性。基本上，删除库或保留降级版本，直到库更新并支持新版本。
