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

v5->v6에서 업데이트 되면서
switch 구문이 삭제 되었음

  <Switch>
  	<Route path='/'><componentname/></Route>
    <Route pate='/componentname2'><componentname2/></Route>
  </Switch>

에서

<Routes>
	<Route path='*' element={<componentname/>}/>
    <Route path='/componentname2' element={<componentname2/>}/>
</Routes>

수정해야 합니다.
