目前，我的nodejs服务器中的所有模块都作为require（）导入，即：

let path = require('path');
let express = require('express');
let http = require('http');
let app = express();

但是我下面的教程将它们导入为：

import express from 'express'
import path from 'path'

引发错误：

SyntaxError: Unexpected token import

我的webpack.config.js设置为：

module: {
    rules: [
        {
            test: /\.js?$/,
            use: 'babel-loader',
            exclude: /node_modules/
        }
    ]
}

在bablerc中：

{
  "presets": ["es2015", "react"]
}

我的软件包版本：

   "babel-core": "^6.7.6",
    "babel-loader": "^6.2.4",
    "babel-preset-es2015": "^6.6.0",
    "babel-preset-react": "^6.5.0",

   "react": "^15.0.1",

  "devDependencies": {
    "babel-cli": "^6.18.0",
    "babel-preset-env": "0.0.3",
    "webpack": "^2.2.1",
    "webpack-dev-middleware": "^1.10.1",
    "webpack-dev-server": "^2.4.1",
    "webpack-hot-middleware": "^2.17.1"
  }

导入可以在我的所有React组件文件中使用，而不能在server.js中使用。如何将服务器从require切换到Import？
