'Switch' is not exported from 'react-router-dom'

在 react-router-dom v6 中，“Switch”被替换为路由“Routes”

1

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

修改成

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

2

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

修改成

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

特别注意 element里面的值是 <Home />
