Nodejs引入模块运行时报错

在做自动化部署的时候，引入包管理，运行脚本的时候报错：

const path = require('path')
const fs = require('fs')
const Client = require('ssh2-sftp-client')

报错信息如下：

PS D:\CODING\Projects\vue-admin-template> node deploy/index.mjs
file:///D:/CODING/Projects/vue-admin-template/deploy/index.mjs:1
const path = require('path')
             ^

ReferenceError: require is not defined in ES module scope, you can use import instead
    at file:///D:/CODING/Projects/vue-admin-template/deploy/index.mjs:1:14
    at ModuleJob.run (internal/modules/esm/module_job.js:183:25)
    at async Loader.import (internal/modules/esm/loader.js:178:24)
    at async Object.loadESM (internal/process/esm_loader.js:68:5)
    at async handleMainPromise (internal/modules/run_main.js:59:12)

根据提示首先将require改成import,运行报错：

PS D:\CODING\Projects\vue-admin-template> node deploy/index.js 
(node:16164) Warning: To load an ES module, set "type": "module" in the package.json or use the .mjs extension.
(Use `node --trace-warnings ...` to show where the warning was created)
D:\CODING\Projects\vue-admin-template\deploy\index.js:1
import { join } from 'path'
^^^^^^

SyntaxError: Cannot use import statement outside a module

根据报错提示，尝试两种解决方案：
1.在package.json中使用"type": "module"：不可行，这将覆盖整个项目，导致项目启动不了。
2.将文件更改为index.mjs，表示引入module模块。最终解决问题。
