Webpack应该摇树了吗？

Question

构建Webpack捆绑包时出现错误。我导入了一个React Spinup组件import { Spinup } from '../../react-website/dist/bundle.esm';，然后看到错误消息说webpack缺少与该包相关但与Spinup组件无关的加载器。我希望Webpack能够智能地仅获取Spinup导入的捆绑软件的部分及其导入（依此类推）。我想念什么？

webpack.config

const path = require('path');

module.exports = {
    entry:  './src/spinup.js',
    output: {
        filename: 'spinup.js',
        path: path.resolve(__dirname, 'dist')
    },
    // module: {
    //     rules: [
    //         { test: /\.js$/, exclude: /node_modules/, loader: "babel-loader" }
    //     ]
    // },
    mode: 'production',
};
