React链接已更改，但页面未更改

Question

我有问题，在它起作用但突然停止之前，我有菜单，当我单击链接更改但页面没有时，如果我刷新页面（f5）可以工作，这就是我的漫游器和菜单- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------：

class TestFeature(unittest.TestCase):

    @classmethod
    def setUpClass(cls, source1, source2):
        # lease resources

    @classmethod
    def tearDownClass(cls):
        # drop leases

    @parameterized.expand(...)      
    def test_feature(self, params):
        ...

} }

导出默认的Usuario；

// ------------------菜单

import React from 'react';
import { Switch, Route } from 'react-router-dom';
import asyncComponent from '../../helpers/AsyncFunc';
import getDevRouters from '../../customApp/router';
import Ini from './ini';
import UsuarioCadastro from '../Cadastro/Usuario'
import Email from '../Email';
import Favoritos from '../Favoritos';

class Usuario extends React.Component {
render() {
const { url } = this.props;
const { propss } = this.props;

return (
  <Switch>

    <Route
      exact
      path={`${url}/cadastro`}
      component={UsuarioCadastro}
    />

    <Route
      exact
      path={`${url}/email`}
      component={Email}
    />

    <Route

      component={Favoritos}
    />

    <Route
