我不明白为什么这个导航下拉菜单不起作用。我的阅读表明它可能与添加 react-popper 依赖项有关，但我真的不明白这是如何实现的。这是 bootstrap 4 beta + create-react-app + reactstrap 5.0.0-alpha.4。遵循 reactstrap文档。

引导代码：

import React, { Component } from 'react';
import logo from './logo.svg';
import './App.css';

class App extends Component {
    render() {
        return (
            <nav className="navbar navbar-expand-sm navbar-light bg-light mb-3">
                <div className="container">
                    <a className="navbar-brand" href="#">
                        Navbar
                    </a>
                    <button
                        className="navbar-toggler"
                        data-toggle="collapse"
                        data-target="#navbarNav"
                    >
                        <span className="navbar-toggler-icon" />
                    </button>
                    <div className="collapse navbar-collapse" id="navbarNav">
                        <ul className="navbar-nav">
                            <li className="nav-item">
                                <a className="nav-link" href="#">
                                    Home
                                </a>
                            </li>
                            <li className="nav-item">
                                <a className="nav-link" href="#">
                                    About
                                </a>
                            </li>
                            <li className="nav-item">
                                <a className="nav-link" href="#">
                                    Services
                                </a>
                            </li>
                            <li className="nav-item">
                                <a className="nav-link" href="#">
                                    Contact
                                </a>
                            </li>
                        </ul>
                    </div>
                </div>
            </nav>
        );
    }
}

export default App;
