webpack.config不起作用，只有我可以看到目录树

Question

我需要一些帮助，我有一个带有webpack的react app，它不起作用。在文章末尾，我会在设置应用程序时附上一张包含结果的图片

package.json

}

webpack.config.js

const path = require('path')

module.exports = {

    entry: path.resolve(__dirname, 'src/index.js'),
    watch: true,
    output: {
        filename: 'bundle.js',
        path: path.resolve(__dirname, 'dist'),
    },
    node: {
        fs: 'empty'
    },
    devServer: {
        open: true
    },
    module: {
        rules: [
            {
                test: /\.(js|jsx)?$/,
                exclude: /(node_modules|bower_components)/,
                use: {
                    loader: 'babel-loader',
                    options: {
                        presets: ['@babel/preset-react', '@babel/preset-env']
                    }
                }
            },
            {
                test: /\.s[ac]ss$/i,
                use: ['style-loader', 'css-loader', 'sass-loader']
            },
        ],
    },
}
