javascript - react-router-dom 不工作只是渲染 "/"

Question

我有一些 throubes 试图渲染多个页面并使用react。我是 React 的新手，这就是为什么我要查看许多页面和教程的原因。我正在使用 React、Webpack、Babel 和 ESLint airbnb

当我渲染我的 React 应用程序时，它看起来像这样。

hows render homepage

我用来渲染所有路由的页面App是这样的

import React from 'react';
import { BrowserRouter, Route, Switch, Redirect } from 'react-router-dom';
import Homepage from './Homepage';
import Layout from '../components/Layout';
import NotFound from './NotFound';
// import NotFound from './NotFound';

function App() {
  return (
    <BrowserRouter>
      <Layout>
        <Switch>
          <Route exact path='/' component={Homepage} />
          <Route exact path='/homepage' component={Homepage} />
          <Route path='/404' component={NotFound} />
          <Redirect from='*' to='/404' />
        </Switch>
      </Layout>
    </BrowserRouter>
  );
}

export default App;

然后当我转到路线/homepage 或任何看起来像这样的路线时

render nothing

NotFound页面代码是这样的

import React from 'react';

function NotFound() {
  return <h1> Error 404: Not Found</h1>;
}

export default NotFound;

我的布局是这样的

import React from 'react';
import Header from './Header';
import Footer from './Footer';

function Layout(props) {
  const { children } = props;
  return (
    <>
      <Header />
      {children}
      <Footer />
    </>
  );
};

export default Layout;

我正在寻找解决问题的答案，也许是我使用的 webpack 配置，但我不确定。 我的 webpack 看起来像这样。

const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const MiniCssExtractPlugin = require('mini-css-extract-plugin');

module.exports = {
  // para definir nuestra entrada index.js y la salida nuestro archivo bunble.js
  entry: './src/index.js',
  output: {
    path: path.resolve(__dirname, 'dist'),
    filename: 'bundle.js',
  },
  //  para resolver nuestros elementos
  resolve: {
    extensions: ['.js', '.jsx'],
  },
  module: {
    rules: [
      {
        test: /\.(js|jsx)$/,
        exclude: /node_modules/,
        use: {
          loader: 'babel-loader',
        },
      },
      {
        test: /\.html$/,
        use: {
          loader: 'html-loader',
        },
      },
      {
        test: /\.(s*)css$/,
        use: [
          { loader: MiniCssExtractPlugin.loader },
          'css-loader',
          'sass-loader',
        ],
      },
      {
        test: /\.(png|gif|jpg)$/,
        use: [
          {
            loader: 'file-loader',
            options: { name: 'assets/[hash].[ext]' },
          },
        ],
      },
    ],
  },
  plugins: [
    new HtmlWebpackPlugin({
      template: './public/index.html',
      filename: './index.html',
    }),
    new MiniCssExtractPlugin({
      filename: 'assets/[name].css',
    }),
  ],
};

还不能评论。 :)

你有没有试过将你的“/”路由移动到 block 的底部，像这样:

        <Switch>
          <Route path='/homepage' component={Homepage} />
          <Route path='/404' component={NotFound} />
          <Route exact path='/' component={Homepage} />
          <Redirect from='*' to='/404' />
        </Switch>
