Reactjs 您不应该使用<；路线渲染>；及<；路线儿童>；在同一路线上&书信电报；路线渲染>；将被忽略 *函数loginpaine（）{ 返回( ( )} /> ); }*

我正试图从'/dashboard'forwared中隐藏所有路由，但我遇到了错误。 有人能帮我弄清楚吗

*function LoginPainel() {
  return (
    <BrowserRouter >
    <Switch>
      <Route exact path='/' render={()=> (
        <Redirect to='/login'/>
      )} />
      <LoginRoute path='/login' component={ Login } />
    </Switch>
    <PrivateRoute path='/dashboard' >
       <div className='main-div'>
       <PrivateRoute component={ DashNavBar } />
       <Switch>
       <React.Fragment>
       <div className='dash-body'>
         <PrivateRoute exact path='/dashboard/home' component={ DashboardHome } />
         <PrivateRoute exact path='/dashboard/list-users' component={ ListUsers } />
         <PrivateRoute exact path='/dashboard/delete-users' component={ DeleteUsers } />
         <PrivateRoute exact path='/dashboard/add-users' component={ AddUsers } />
         <PrivateRoute exact path='/dashboard/update-users' component={ UpdateUsers } />
         </div>
         </React.Fragment>
       </Switch>
     </div>
     </PrivateRoute>
    </BrowserRouter>
  );
}*
