自关闭一个组件后出现无效的钩子调用错误

Question

错误：无效的钩子调用。钩子只能在函数组件的主体内部调用。这可能是由于以下原因之一：

1. React和渲染器的版本可能不匹配（例如React DOM）
2. 你可能违反了钩子的规则
3. 同一个应用程序中可能有多个React副本请参见reactjs。org/link/invalid hook call获取有关如何调试和修复此问题的提示

./src/index.js/

5 |从导入reportWebVitals/报告“生命体征”；6 |导入“./node_模块/bootstrap/dist/css/bootstrap.min.css”；7 |从'react Router dom'导入{BrowserRouter as Router}；

8 |反应。渲染（9 | 10 | 11 |），

在应用程序中包含导航组件后。js文件无效钩子调用错误，下面是我的应用程序。js文件代码

import React from "react";
import Home from "./components/Home";
import About from "./components/About";
import { Route, Switch } from "react-router-dom";
import Navigation from "./Navigation";
export default function App() {
  return (
    <div className="app">
      <Navigation />
      <Switch>
        <Route path="/about" component={About} />
        <Route path="/" component={Home} />
      </Switch>
    </div>
  );
}

删除导航组件后，错误不会出现在索引下面。js文件代码

import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import reportWebVitals from './reportWebVitals';
import "../node_modules/bootstrap/dist/css/bootstrap.min.css";
import { BrowserRouter as Router} from 'react-router-dom';
ReactDOM.render(
  <Router>
    <App/>
  </Router>,
  document.getElementById('root')
);

// If you want to start measuring performance in your app, pass a function
// to log results (for example: reportWebVitals(console.log))
// or send to an analytics endpoint. Learn more: 
reportWebVitals();

navigation.js

import { Navbar, Nav, Container } from 'react-bootstrap';
import React from 'react'

export default function Navigation() {
    return (
        <>
        <Navbar collapseOnSelect fixed="top" expand="sm" bg="dark" variant="dark">
            <Container>
            <Navbar.Toggle aria-controls="responsive-navbar-nav" />
            <Navbar.Collapse id="responsive-navbar-nav">
                <Nav>
                <Nav.Link href="/">Home</Nav.Link>
                <Nav.Link href="/about">About</Nav.Link>

                </Nav>
                </Navbar.Collapse>
            </Container>
        </Navbar>
        </>
    )
}

谁能帮我解决这个问题？
