To ensure that your react-router renders components when the URL changes, you need to properly configure your routes in your React application. Here are some steps to follow:

1. Install and import the necessary dependencies: First, you need to install and import the necessary dependencies for react-router, including react-router-dom.

2. Set up your routes: Next, you need to define your routes in your application. You can do this by creating a Router component and defining your routes as Route components inside it. Each Route component should have a path attribute that corresponds to the URL path and a component attribute that specifies which component to render.

3. Wrap your app with the Router component: After defining your routes, you need to wrap your entire application with the Router component so that it can handle the routing for you.

4. Ensure that your components are properly rendered: Finally, you need to ensure that your components are properly rendered. You can do this by using the Switch component inside your Router component to indicate which component to render for a particular URL path.

Here is an example of how to set up your routes in your React application:

import { BrowserRouter as Router, Route, Switch } from 'react-router-dom';
import Home from './components/Home';
import About from './components/About';

function App() {
  return (
    <Router>
      <Switch>
        <Route exact path="/" component={Home} />
        <Route path="/about" component={About} />
      </Switch>
    </Router>
  );
}

In this example, we’ve defined two routes: one for the home page and one for the about page. When the user navigates to the home page, the Home component will be rendered, and when they navigate to the about page, the About component will be rendered.

Make sure that your components are properly defined and imported as well. With this setup, your react-router will render the appropriate component when the URL changes.
