Node.js v18.8.0

解决办法

如果使用的是 visual studio code，在终端处输入
windows系统输入

$env:NODE_OPTIONS="--openssl-legacy-provider" 
或
set NODE_OPTIONS=--openssl-legacy-provider
 
补充:
在终端输入一次只能本次生效，如果想永久生效可以在 package.json 文件中修改对应的 scripts 节点的内容如下：
 
"serve": "SET NODE_OPTIONS=--openssl-legacy-provider && vue-cli-service serve",
"build": "SET NODE_OPTIONS=--openssl-legacy-provider && vue-cli-service build",

linux输入

export NODE_OPTIONS=--openssl-legacy-provider

最直接的办法

将 node.js 版本降到 v16+
