【问题描述】：
我刚刚升级到单声道 4.8.0。
在运行我的 nancy 应用程序时，我现在收到了这个无法描述的错误：
[ERROR] FATAL UNHANDLED EXCEPTION: System.InvalidOperationException: Something went wrong when trying to satisfy one of the dependencies during composition, make sure that you've registered all new dependencies in the container and inspect the innerexception for more details. ---> Nancy.TinyIoc.TinyIoCResolutionException: Unable to resolve type: Nancy.NancyEngine ---> Nancy.TinyIoc.TinyIoCResolutionException: Unable to resolve type: Nancy.Routing.DefaultRequestDispatcher ---> Nancy.TinyIoc.TinyIoCResolutionException: Unable to resolve type: Nancy.Routing.DefaultRouteResolver ---> Nancy.TinyIoc.TinyIoCResolutionException: Unable to resolve type: Nancy.Routing.RouteCache ---> System.NullReferenceException: Object reference not set to an instance of an object
它说有一些依赖项没有正确注册。但是，通常情况下，这伴随着（沿着内部异常链）伴随着无法解决依赖的指示。
现在它只是说Unable to resolve type: Nancy.NancyEngine，这是一个我确信我不需要为此修改的类。此外，在堆栈跟踪的末尾（通常有一个线索表明是哪个依赖导致了这种情况），它显示Unable to resolve type: Nancy.Routing.RouteCache ---> System.NullReferenceException: Object reference not set to an instance of an object
下面是完整的堆栈跟踪。我错过了什么？感谢您对此事的任何见解！
