有没有办法package.json在nodejs应用程序中设置版本？我想要这样的东西

var port = process.env.PORT || 3000
app.listen port
console.log "Express server listening on port %d in %s mode %s", app.address().port, app.settings.env, app.VERSION

我试图使用Webpack与Babel编译ES6资产,但我收到以下错误消息:

You may need an appropriate loader to handle this file type.
| import React from 'react';
| /*
| import { render } from 'react-dom'

这是我的Webpack配置的样子:

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

module.exports = {
  entry: './index',
  output: {
    path: path.join(__dirname, 'dist'),
    filename: 'bundle.js',
    publicPath: '/dist/'
  },
  module: {
    loaders: [
      {
        test: /\.jsx?$/,
        loader: 'babel-loader',
        exclude: /node_modules/
      }
    ]
  }
}

以下是使用Webpack的中间件步骤:

var webpack = require('webpack');
var webpackDevMiddleware = require('webpack-dev-middleware');
var config = require('./webpack.config');

var express …

node v10.23.0 操作系统：MacOS Catalina 10.15.7

错误：不应从默认导出模块导入命名的导出“版本”（导入为“版本”）（仅默认导出很快可用）

我正在使用以下 webpack 配置：
