React-router npm package give me warning in console? (PropTypes is deprecated)

Question

I have a very basic responsive application that I am currently creating using the create-react-app, and this is the code:

index.js

import React from 'react';
import ReactDOM from 'react-dom';
import { Router, Route } from 'react-router';

import createBrowserHistory from 'history/createBrowserHistory';

import App from './App/AppComponent';

const browserHistory = createBrowserHistory();

ReactDOM.render(
    <Router path="/" history={browserHistory}>
        <div>
            <Route path="/" component={App} />
        </div>
    </Router>, document.getElementById('root')
);

AppComponent.js

import React, { Component } from 'react';

class App extends Component {
    render() {
        return (
            <div>This is the App component</div>
        );
    }
}

export default App;

And I get the following warning in the console when starting this application:

bundle.js:11888 Warning: Accessing PropTypes via the main React package is deprecated. Use the prop-types package from npm instead.

When I delete the reaction-related material related to the router, I do not seem to receive a console warning, so I assume that it comes from this package ... but I used it in another small application earlier and did not have an error. so I'm a little confused.

What am I missing here?
