我剛剛從NuGet安裝了新的Ninject.MVC3，並試圖使它在我的asp.net mvc 3應用程序中工作，但是當我在衝浪時偶爾出現這個奇怪的錯誤我的網站：Ninject +「加載Ninject組件ICache時出錯」
[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.

而且我的代碼是：
// AppStart_NinjectMVC3.cs
using System.Web.Mvc;
using Ninject.Modules;

}
}
}
// NinjectHttpApplicationModule.cs
using MyApp.Data;
using NHibernate;
namespace MyApp
{
using System;
using System.Web;
using Ninject;
using Ninject.Web.Mvc;

bootstrapper.Initialize(CreateKernel);
}
}

{

{

return;
}

}
}
#endregion

return kernel;
}

private static void RegisterServices(IKernel kernel)
{
kernel.Bind<ISession>().ToMethod(x => kernel.Get<SessionFactoryBuilder>().CreateFactory().OpenSession()).InRequestScope();

kernel.Bind(typeof(IRepositoryBase<>)).To(typeof(RepositoryBase<>));
kernel.Bind<IUnitOfWork>().To<UnitOfWork>();
}
}
}
大部分代碼是默認的一個通過的NuGet安裝時你..我做的唯一事情就是一些綁定添加到RegisterServices()
有什麼建議？
