react-router v4浏览器路由器不起作用

Question

我不知道代码中的差异是什么。

webpack.config.js

const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const AsyncChunkNames = require('webpack-async-chunk-names-plugin');
const lunaRocketModulesPath = path.resolve(__dirname, 'luna-rocket');

module.exports = {
    entry: [
        '@babel/polyfill',
        path.join(__dirname,'src/app','app.js')

        path: path.join(__dirname,'build'),
        filename: 'index.bundle.js',

        publicPath: '/', // 헐랭이.. 이 게 뭐길래...
    },

        alias: {
            'luna-rocket': lunaRocketModulesPath

        ],

    },

                }
            }
        }
    }
};

app.js

import React, { Suspense, lazy } from 'react'
import ReactDOM from 'react-dom'
import { BrowserRouter as Router, Route, Switch, HashRouter, withRouter, useRouterHistory , Redirect} from 'react-router-dom'
import Home from './Home';
import RocketComponent from './RocketComponent';

const Loading = () => <div>loading...</div>


ReactDOM.render(
    <Router>
                <div className="app">
                    <div className="container">
                        <Suspense fallback={<Loading />}>
                            <Route exact path="/" component={Home} />
                            <Route path="/rocket" component={RocketComponent} />
                        </Suspense>
                    </div>
                </div>
    </Router>,
    document.getElementById('app')
);

RocketComponent.js

import HeaderNew from "./HeaderNew";
import React, {lazy, Suspense} from 'react';
import RocketMenuNew from "./RocketMenuNew";
import {Route, Switch} from "react-router-dom";

function scrollToTop() {
    document.body.scrollTop = 0
}

const menuData = [
    {
        title: "LUXAccordion",
        path: "/rocket/LUXAccordion",
        component: "./Documents/LUXAccordion/AccordionDocument"
    },
    {
        title: "LUXActionBar",
        path: "/rocket/LUXActionBar",
        component: "./Documents/LUXActionBar/ActionBarDocument"
    },
    {
        title: "LUXBadge",
        path: "/rocket/LUXBadge",
        component: "./Documents/LUXBadge/BadgeDocument"
    },
    {
        title: "LUXButton",
        path: "/rocket/LUXButton",
        component: "./Documents/LUXButton/ButtonDocument"
    }
]

function DynamicLoader(props) {
        // console.log("title", `./Documents/${title.title}/${title.title.substring(3)}Document`)
        // const LazyComponent = React.lazy(() => import(`./Documents/${title.title}/${title.title.substring(3)}Document`));

    const LazyComponent = lazy(() => import(`${props.component}`));
    console.log("LazyComponent", LazyComponent)
    return (
            <LazyComponent />
    );
}


class RocketComponent extends React.Component {
    render() {
        console.log("this.props.match.path", this.props.match.path)
        return (
            <div className="documents-new">
                <HeaderNew />
                <RocketMenuNew />
                <Switch>
                    {menuData.map((props, i) => {
                        return <Route path={props.path} render={() => <DynamicLoader component={props.component}/>} key={i}/>
                    })}
                </Switch>
            </div>
        );
    }
}

export default RocketComponent

此代码有效。 但是RocketComponent.js移到路由目录。不管用。 我不知道为什么？

RocketComponent.js->路径：app / router / RocketComponent.js

import HeaderNew from "./../HeaderNew";
import React, {lazy, Suspense} from 'react';
import RocketMenuNew from "./../RocketMenuNew";
import {Route, Switch} from "react-router-dom";

function scrollToTop() {
    document.body.scrollTop = 0
}

const menuData = [
    {
        title: "LUXAccordion",
        path: "/rocket/LUXAccordion",
        component: "./../Documents/LUXAccordion/AccordionDocument"
    },
    {
        title: "LUXActionBar",
        path: "/rocket/LUXActionBar",
        component: "./../Documents/LUXActionBar/ActionBarDocument"
    },
    {
        title: "LUXBadge",
        path: "/rocket/LUXBadge",
        component: "./../Documents/LUXBadge/BadgeDocument"
    },
    {
        title: "LUXButton",
        path: "/rocket/LUXButton",
        component: "./../Documents/LUXButton/ButtonDocument"
    }
]

function DynamicLoader(props) {
    const LazyComponent = lazy(() => import(`${props.component}`));
    return (
            <LazyComponent />
    );
}

class RocketComponent extends React.Component {
    render() {

        return (
            <div className="documents-new">
                <HeaderNew />
                <RocketMenuNew />
                <Switch>
                    {menuData.map((props, i) => {
                        return <Route path={props.path} render={() => <DynamicLoader component={props.component}/>} key={i}/>
                    })}
                </Switch>
            </div>
        );
    }
}

export default RocketComponent

我修改了组件路径，而app.js修改了RocketComponent路径权限。
但不起作用 错误是 为什么不起作用，路径正确，请帮助我。 我的webpack是4，babel 7
