react-router : run is not a function

All we need is an easy explanation of the problem, so here it is.

A Egghead tutorial teaches it like this:

var React = require('react');
var Router = require('react-router');
var routes = require('./config/routes');, function(Root){
  React.render(<Root />, document.getElementById('app'));

Yet I get this error:

Uncaught TypeError: is not a function

I’ve already updated react-router to the recent version.

How to solve :

I know you bored from this bug, So we are here to help you! Take a deep breath and look at the explanation of your problem. We have many solutions to this problem, But we recommend you to use the first method because it is tested & true method that will 100% work for you.

Method 1

Since the release of React Router v1.0, the run method has been removed, these breaking changes are documented in the upgrade guide. Your code would roughly translate to this:

ReactDOM.render(<Router>{routes}</Router>, document.getElementById('app'))

Note: Use and implement method 1 because this method fully tested our system.
