我正在尝试实现useHistory钩子react-router-dom，但它似乎不起作用。抛出无效的钩子调用

应用程序.js

import React, { Component } from 'react';

            <>
               <...>
                <Router>
                    <AuthProvider>
                        <Switch>
                            <Route exact path="/" component={Signup} />
                            <Route path="/signup" component={Signup} />
                            <Route path="/login" component={Login} />
                            <Route path="/account" component={Account} />
                        </Switch> …
