我刚刚从NuGet安装了新的Ninject.MVC3并试图让它在我的asp.net mvc 3应用程序中运行,但是我现在得到这个奇怪的错误,然后在浏览我的网站时:
[InvalidOperationException: Error loading Ninject component ICache No such component has been registered in the kernel's component container. Suggestions: 1) If you have created a custom subclass for KernelBase,ensure that you have properly implemented the AddComponents() method. 2) Ensure that you have not removed the component from the container via a call to RemoveAll(). 3) Ensure you have not accidentally created more than one kernel. ] Ninject.Components.ComponentContainer.Get(Type component) in d:BuildAgent-01workb68efe9aafe8875esrcNinjectComponentsComponentContainer.cs:146 Ninject.Components.ComponentContainer.Get() in d:BuildAgent-01workb68efe9aafe8875esrcNinjectComponentsComponentContainer.cs:102 Ninject.KernelBase.CreateContext(IRequest request,IBinding binding) in d:BuildAgent-01workb68efe9aafe8875esrcNinjectKernelBase.cs:540 Ninject.<>c__DisplayClassa.<Resolve>b__6(IBinding binding) in d:BuildAgent-01workb68efe9aafe8875esrcNinjectKernelBase.cs:375 System.Linq.<>c__DisplayClass12`3.<CombineSelectors>b__11(TSource x) +20 System.Linq.WhereSelectEnumerableIterator`2.MoveNext() +151 System.Linq.Enumerable.SingleOrDefault(IEnumerable`1 source) +4178557 Ninject.Web.Mvc.NinjectDependencyResolver.GetService(Type serviceType) in c:ProjectsNinjectninject.web.mvcmvc3srcNinject.Web.MvcNinjectDependencyResolver.cs:56 System.Web.Mvc.DefaultControllerActivator.Create(RequestContext requestContext,Type controllerType) +51 [InvalidOperationException: An error occurred when trying to create a controller of type 'MyApp.Controllers.NewsController'.

已在2.2.1.0中修复
