我已经利用NavLink样式将活动类添加到当前页面菜单项链接中。我也在Navs中使用“精确”。但是，我无法从主页上删除活动的类。任何人都可以看看我的代码，看看我是否缺少什么吗？谢谢。代码如下。 ：
app.js-
import React, { Component } from 'react';
import './App.css';
import { HashRouter as Router, Route } from 'react-router-dom';
import Inicio from './pages/Inicio';
import Gamification from './pages/Gamification';
import TotalMultimedia from './pages/TotalMultimedia';
import ELearning from './pages/ELearning';
import AbsoluteEngagement from './pages/AbsoluteEngagement';
import Nosotros from './pages/Nosotros';
import Contacto from './pages/Contacto';
class App extends Component {
render() {
return (
<Router basename="/">
<div>
<Route exact path='/' component={Inicio} />
<Route exact path='/Gamification' component={Gamification} />
<Route exact path='/TotalMultimedia' component={TotalMultimedia} />
<Route exact path='/ELearning' component={ELearning} />
<Route exact path='/AbsoluteEngagement' component=
{AbsoluteEngagement} />
<Route exact path='/Nosotros' component={Nosotros} />
<Route exact path='/Contacto' component={Contacto} />
</div>
</Router>
);
}
}
export default App;
Navbar.js-
import React, { Component } from 'react';
import './Navbar.css';
import { NavLink } from 'react-router-dom';
const isActivefunc = (match, location) => {
console.log(match, location)
return match
}
class Navbar extends Component {
render() {
return (
<div className="nav-wrapper">
<nav className="navbar nav-container pb-3 navbar-expand-md navbar-dark overlay">

我发现了问题。我只是忘了删除我复制的引导程序示例附带的活动类（剪切和粘贴的危险）。可以在Navbar.js文件中的nav-item类之后看到该问题。
