Router Not defiend،!

im using this code for import StaticRouter in the Server And BrowserRouter in the Client .

if (Meteor.isClient) {
    import { BrowserRouter as Router } from "react-router-dom";
    import { StaticRouter as Router } from "react-router-dom";

I actually did this for ssr.
But the server gives an error :

Router not defined :

How to dynamic this import . For SSR ?

Does anyone have any suggestions for dynamizing these imports?

Which version of React Router do you use? We just import those:

import {Route, Router, Switch} from 'react-router';
import {createBrowserHistory, createMemoryHistory} from "history";
const customHistory = Meteor.isClient ? createBrowserHistory() : createMemoryHistory();
    <Router history={customHistory}>

Only history is different for the server with version:

"react-router": {
      "version": "5.2.0",

edit: Aha, found that I did not do it optimally: your import from react-router-dom seems correct. I followed those examples of imports: which import straight from react-router. Will need to take a look later whether that can solve your issues.

i import this :

    "react": "^16.13.1",
    "react-bootstrap": "^1.3.0",
    "react-dom": "^16.13.1",
    "react-helmet": "^6.1.0",
    "react-helmet-async": "^1.0.7",
    "react-router-dom": "^5.2.0",

what should i really do ?
