Razzle: get warning when fresh install and start

[aminsource]

I new to razzle, when I install it and start it I get following warning in console? How i solve them?

Warning: Please use require("react-router-dom").Route instead of require("react-router-dom/Route"). Support for the latter will be removed in the next major release.

Warning: Please use require("react-router-dom").Switch instead of require("react-router-dom/Switch"). Support for the latter will be removed in the next major release.

Warning: Please use require("react-router-dom").BrowserRouter instead of require("react-router-dom/BrowserRouter"). Support for the latter will be removed in the next major release.

My Node is v10.15.1 and npm is 6.9.0

in template need change in client.js

 import BrowserRouter from 'react-router-dom/BrowserRouter';

to

 import {BrowserRouter}  from 'react-router-dom';

and in App.js

import Route from 'react-router-dom/Route';
import Switch from 'react-router-dom/Switch';

to

import {Route,Switch} from 'react-router-dom';
