我是 react-router 新手(https://github.com/rackt/react-router)。我在做出这样的反应后将其包括在内:
<script src="http://fb.me/react-0.12.2.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/reactrouter/0.13.2/ReactRouter.js"></script>
我收到一个错误:Uncaught TypeError: Super expression must be null or a function, not undefined
我做错什么了?
