Webpack踩坑——Webpack-dev-server无法自动更新

如下所示，设置了webpack-dev-server后修改html代码页面无法更新，网上搜了一大堆说什么需要设置hot和inline发现都不行，最后发现是因为在package.json中配置了 browserslist字段，删了就可以了。

const HtmlWebpackPlugin = require(html-webpack-plugin);
const {
          
    resolve } = require(path);
module.exports = {
          
   
    entry: ./src/js/index.js,
    output: {
          
   
        filename: js/build.js,
        path: resolve(__dirname, build)
    },
    module: {
          
   
        rules: [
            // loader的配置
            {
          
   
                // 处理less资源
                test: /.less$/,
                use: [style-loader, css-loader, less-loader],
            },
            {
          
   
                // 处理css资源
                test: /.css$/,
                use: [style-loader, css-loader],
                // outputPath: css
            },
            {
          
   
                // 处理图片资源
                test: /.(jpg|png|gif|jpeg)$/,
                loader: url-loader,
                options: {
          
   
                    limit: 8 * 1024,
                    name: [hash:10].[ext],
                    // 关闭es6模块化
                    esModule: false,
                    // 设置图片输出的路径
                    outputPath: images/
                }
            },
            {
          
   
                // 处理html
                test: /.html$/,
                loader: html-loader
            },
            {
          
   
                // 处理其他资源
                exclude: /.(html|css|js|less|jpg|jpeg|gif|png)$/,
                loader: file-loader,
                options: {
          
   
                    name: [hash:10].[ext],
                    outputPath: compontents
                }
            }
        ]
    },
    plugins: [
        // plugins的配置
        new HtmlWebpackPlugin({
          
   
            template: ./src/index.html
        })
    ],
    devServer: {
          
   
        contentBase: resolve(__dirname, build),
        compress: true,
        port: 3000,
        open: true,
        // inline: true
    },
    mode: development
}

//注意事项：webpack-dev-server在更新的时候要去掉package.json中的browserslist字段

    },
