运行dnvm upgrade时，我收到了一个无用的例外：
C:\Users\...\Visual Studio 2015\Projects\foo>dnvm upgrade
Determining latest version
Unable to find any runtime packages on the feed!
At C:\Users\banksd\.dnx\bin\dnvm.ps1:483 char:9
+ throw "Unable to find any runtime packages on the feed!"
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : OperationStopped: (Unable to find ...es on the feed!:String) [], RuntimeException
+ FullyQualifiedErrorId : Unable to find any runtime packages on the feed!
我也无法在新的ASP.NET 5项目中解析"Microsoft.AspNet.StaticFiles": "1.0.0-rc1-final"。
不知道这两者是否相关。
有任何建议吗？
