Error Invariant Violation Element type is invalid expected a string for built-in components or a class function but got object

Question

This is my code:

var React = require('react')
var ReactDOM =  require('react-dom')
var Router = require('react-router')
var Route = Router.Route
var Link = Router.Link

var App = React.createClass({
  render() {
    return (
      <div>
        <h1>App</h1>
        <ul>
          <li><Link to="/about">About</Link></li>
        </ul>
      </div>
    )
  }
})

var About = require('./components/Home')
ReactDOM.render((
  <Router>
    <Route path="/" component={App}>
      <Route path="about" component={About} />
    </Route>
  </Router>
), document.body)

My Home.jsx file:

var React = require('react');
var RaisedButton = require('material-ui/lib/raised-button');

var Home = React.createClass({
  render:function() {
    return (
        <RaisedButton label="Default" />
    );
  },
});

module.exports = Home;

I am getting this error:

Uncaught Error: Invariant Violation: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: object.

How to fix?

Hello @kartik,

You need export default or require(path).default

var About = require('./components/Home').default

Hope it helps!!

Thank You!
