控制台报错：

原因分析：

提示：这里填写问题的分析：

js文件中，使用了

import***from***

的方法，配合package.json配置文件来可以正常运行。去掉配置文件会发现，单独运行js文件也会报错和在python中调用一样的错。

// const cryptoJs = require('crypto-js')
import cryptoJs from 'crypto-js';

解决方案：

将js文件中使用import引入方式改一下即可

 const cryptoJs = require('crypto-js')
// import cryptoJs from 'crypto-js';
