我想在同一个导航链接上使用 react-router 和 react-scroll。如果我在主页上，我希望按钮具有反应滚动行为。如果我在不同的页面上，按钮需要返回主页，然后滚动到首选组件（反应滚动行为）

这是我想到的，但它不能正常工作。

import { Link } from 'react-router-dom';
import { Link as LinkRoll } from 'react-scroll'

                           <Link
                               to='/'
                               className='nav-links'
                           >
                               <LinkRoll
                                   activeClass='active'
                                   to='about'
                                   spy={true}
                                   smooth={true}
                                   offset={-70}
                                   duration={500}
                                   onClick={closeMobileMenu}
                               >
                                   About
                               </LinkRoll>
                           </Link>

应用程序.js

import React from 'react';
import { BrowserRouter as Router, Route, Redirect } from 'react-router-dom';
import './style.css';

import Navigation from './Navigation';
import Home from './Home';
import Other from './Other';

export default function App() {
  return (
    <Router>
      <Navigation />
      <Route path="/home">
        <Home />
      </Route>
      <Route path="/other">
        <Other />
      </Route>
      <Route exact path="/">
        <Redirect to="/home" />
      </Route>
    </Router>
  );
}

导航.js

import React from 'react';
import { NavLink, useLocation, useHistory } from 'react-router-dom';
import * as Scroll from 'react-scroll';

export default function Navigation() {
  const path = useLocation().pathname;
  const location = path.split('/')[1];
  const history = useHistory();
  const scroller = Scroll.scroller;

  const scrollToAnchor = () => {
    scroller.scrollTo('anchor', {
      duration: 1500,
      delay: 100,
      smooth: true,
      offset: 50
    });
  };

  const goToHomeAndScroll = async () => {
    await closeMobile();
    await history.push('/');
    await scroller.scrollTo('anchor', {
      duration: 1500,
      delay: 100,
      smooth: true,
      offset: 50
    });
  };

  const closeMobile = () => {};

  return (
    <div className="container">
      <div className="navigation">
        <NavLink to="/home" activeClassName="active">
          Home
        </NavLink>
        <NavLink to="/other" activeClassName="active">
          Other Page
        </NavLink>
      </div>
      {location === 'home' ? (
        <button onClick={scrollToAnchor}>Scroll to anchor</button>
      ) : (
        <button onClick={goToHomeAndScroll}>
          Go to Home and Scroll to anchor
        </button>
      )}
    </div>
  );
}

主页.js

import React from 'react';
import * as Scroll from 'react-scroll';

export default function Home() {
  const Element = Scroll.Element;

  return (
    <div>
      <h1>Home</h1>
      <p>Welcome</p>
      <p>
        Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed gravida
        fermentum purus egestas blandit. Nam nisl sem, feugiat hendrerit magna

export default function Other() {
  return (
    <>
      <h1>Other page</h1>
      <p>blablabla</p>
    </>
