我刚刚在Windows上安装了Lumen,不幸的是我收到以下错误:

NotFoundHttpException in Application.php line 1093:

in Application.php line 1093
at Application->handleDispatcherResponse(array('0')) in Application.php line 1063
at Application->dispatch(null) in Application.php line 1006
at Application->run() in index.php line 28

这可能是什么问题？
