[Solved] export ‘Switch’ (imported as ‘Switch’) was not found in ‘react-router-dom’

In react-router-dom v6, Switch is replaced by routes Routes.

You need to update the import from:

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

to:

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

You also need to update the Route declaration from:

<Route path="/" component={Home} />

to:

<Route path='/welcome' element={<Home/>} />
