How does a REACT project use hashrouter to control history when using react-router-dom 4.0 or later?

When history is not added, clicking link back and forth will report the following error in the console:

Warning: Hash history cannot push the same path; a new entry will not be added to the history stack

The solution is to install and use the history module.

import createBrowserHistory from "history/createBrowserHistory";
const customHistory = createBrowserHistory();

<Router history  = {customHistory} />

Note that the introduced hashrouter is changed to a router.
