记录一个npm run dev 报错的问题。
今天在家里电脑跑npm run dev的时候报错，报错内容如下:

第一时间去找了度娘，也确实解决了，但不得不说网上还是有一些错误的答案的。
这个问题是由于node版本过高导致的，所以有一种方案便是降低node版本，正常来讲17一下就是ok的。
另外一种方案就是在命令行执行前设置下环境变量，用代码来看就是在package.json文件中修改如下内容:

"scripts": {
   "dev": "SET NODE_OPTIONS=--openssl-legacy-provider && vue-cli-service serve",
   "build:prod": "SET NODE_OPTIONS=--openssl-legacy-provider &&  && vue-cli-service build",
   "build:stage": "SET NODE_OPTIONS=--openssl-legacy-provider && && vue-cli-service build --mode staging",
   "preview": "SET NODE_OPTIONS=--openssl-legacy-provider &&  && node build/index.js --preview",
   "lint": "SET NODE_OPTIONS=--openssl-legacy-provider &&  && eslint --ext .js,.vue src"
 },

看着很简单，无非就是在正常的命令前加了SET NODE_OPTIONS=--openssl-legacy-provider,需要注意的是等号后面是两个-，有的文章写的是一个-，我自己测试一个-是有问题的，故此记录。
希望能帮助到需要的朋友。
