Problem when rendering view (react-router 1.0) undefined component

I can not render the view, my code is like the following example server .

When I run the server:

Warning: React.createElement: type should not be null, undefined, boolean, or number. It should be a string (for DOM elements) or a ReactClass (for composite components).

{ [Invariant Violation: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined.] name: 'Invariant Violation', framesToPop: 1 }

And this shows me when I make a log to renderProps :

{ routes: 
   [ { childRoutes: [Object] },
     { path: '/',
       component: [Function: BaseAdmin],
       indexRoute: [Object],
       childRoutes: [Object] },
     { component: [Function: Home] } ],
  params: {},
  location: 
   { pathname: '/',
     search: '',
     hash: '',
     state: null,
     action: 'POP',
     key: 'zljum4',
     query: {},
     '$searchBase': { search: '', searchBase: '' } },
