Reactjs 反应路由器不改变路径

我想你必须把它修好

{/*  */}

参考此

试着放在第一位。

import * as React from "react";
import { BrowserRouter as Router,Switch,Route,Link,useHistory } from "react-router-dom";
import Login from "./login/index";
import MainFrame from "./main-frame/index";

const MainWrapper = () => {

  return (
    <div>
      <Router>      
      <Switch>
          <Route path="/main-frame">
          <MainFrame  /> 
          </Route>
          <Route exact path="/">
          <Login />
          </Route> 
          <Route exact path="/i">
          <p>sdf</p>
          </Route>       
        </Switch>
      </Router> 
    </div>
  );
};

export default MainWrapper;

Cannot GET /i

Cannot GET /main-frame
