vue2老项目从mac还到windows环境跑不起来，npm无法安装

今天把之前的老项目在windows跑了一下，发现跑步起来，报错内容如下

刚刚开始以为是 nodejs版本的问题，因为本地nodejs 是20了，package.json 版本是
{
"name": "bk-zhoulujun",
"version": "0.1.24",
"private": true,
"engines": {
"node": "^v16.15.0",
"npm": "^8.5.5"
},
}于是使用 nvm use 16.15.0 试一试，还是一样的。
谷哥搜了一下，也有这么说的，比如：webpackage依赖安装报错ERESOLVE unable to resolve dependency tree https://blog.csdn.net/qq_34137073/article/details/113646342
其是，只需
npm i --legacy-peer-deps
