【node 运行项目报错】 使用node最新版本，运行旧项目报错

起因

node 升级到最新的版本v18之后运行之前的项目报错

### 解决 
pakeage.json文件中，修改package.json，在相关构建命令之前加入SET NODE_OPTIONS=--openssl-legacy-provider，

“scripts”: {
“serve”: “SET NODE_OPTIONS=–openssl-legacy-provider && vue-cli-service serve”,
“build”: “SET NODE_OPTIONS=–openssl-legacy-provider && vue-cli-service build”
},

"scripts": {
   "serve": "SET NODE_OPTIONS=--openssl-legacy-provider && vue-cli-service serve",
   "build": "SET NODE_OPTIONS=--openssl-legacy-provider && vue-cli-service build"
},

再执行 npm run serve 就可以运行项目了，如果不行 新开一个窗口再执行一下npm run serve

原因

node.js 的版本问题

因为 node.js V17版本中最近发布的OpenSSL3.0, 而OpenSSL3.0对允许算法和密钥大小增加了严格的限制，可能会对生态系统造成一些影响。故此以前的项目在升级 nodejs 版本后会报错。
