我正在尝试在 os x 上运行 aspnet 5 的示例： git clone https://github.com/shirhatti/Home.git
当我构建项目 HelloMvc -- 'kpm build' -- 没关系。然后我使用“k kestrel”运行应用程序并看到以下错误：

谷歌没有确切的问题。我试图重新安装 kvm，删除并签出 NuGet 部门。
更新：当我尝试通过“k web”运行同一个项目时，Windows 上的类似行为：

似乎问题出在 Microsoft.AspNet.Mvc.* 程序集中引用的一个（或多个）中。这是来自 Microsoft.AspNet.Mvc.Core 的 DefaultAssemblyProvider 的反汇编。我猜问题出在 ILibraryManager 的实现 GetReferenceLibraries() 方法中。但我找不到这个实现。
public class DefaultAssemblyProvider : IAssemblyProvider
{
private static readonly HashSet<string> _mvcAssemblyList;
private readonly ILibraryManager _libraryManager;
public IEnumerable<Assembly> CandidateAssemblies
{
get
{
