报错信息：

【报错】Message.js 导入方式不对，用的是 ES Moudle 的语法，提示使用 import 引入文件

项目开发没有用到 js-message 依赖，是 node-ipc 依赖中用到的 js-message 依赖， node-ipc 中限制 js-message 版本： “js-message”: “>=1.0.5”, ，安装 js-message 时版本不一致导致报错

方法1：
修改项目package.json文件，添加

  "express": "^4.17.1",
    "js-message": "1.0.7",

方法2：
由于node和npm的版本不匹配，修改node和npm的版本
