webpack 开发服务器不服务但编译

如何解决webpack 开发服务器不服务但编译

我正在尝试为 React 设置一个基本的 webpack 配置，并使用 webpack 开发服务器在开发模式下提供它。 Webpack 可以很好地编译所有内容，但是在使用 webpack 开发服务器时不提供文件...我将项目托管在 VPS 上，并使用样板 create-react-app 开发服务器测试了服务器是否可访问 - 确实如此。我可以看到该项目很好地转到“http://serverIPv4:3000”。 Webpack 开发服务器项目配置为在端口 9000 上提供服务 - 即使正在编译文件，这也不起作用。它也不适用于默认端口 8080 或 3000。我缺少什么？

webpack.config.js：

const webpack = require('webpack');
const path = require('path');

const config = {
    entry: './src/index.js',output: {
        path: path.resolve(__dirname,'dist'),filename: 'bundle.js'
    },module: {
        rules: [
            {
                test: /\.(js|jsx)$/,use: 'babel-loader',exclude: /node_modules/
            },{
                test: /\.css$/,use: [
                    'style-loader','css-loader'
                ]
            }
        ]
    },resolve: {
        extensions: [
            '.js','.jsx'
        ]
    },devServer: {
        contentBase: path.resolve(__dirname,compress: true,port: 9000
    },};

module.exports = config;
