在yarn安装node项目依赖时提示  error Error: getaddrinfo ENOTFOUND registry.nlark.com at GetAddrInfoReqWrap.onlookupall [as oncomplete] (node:dns:118:26)

出现了类似这种 error Error: getaddrinfo ENOTFOUND xxx 的情况就是说对应的xxx地址找不到或者失效了。 导致这个的原因可能是你的当前项目中的  yarn.lock 文件中引用了一个已经失效的地址.

解决方法：  删除这个yarn.lock文件 或者其他  *.lock 文件后重新执行  yarn 或者npm install

如果你不使用yarn，直接改为 npm install 则可能会出现其他诡异的异常， 如：

m verb node v12.22.12
npm verb npm  v6.14.16
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! mozjpeg@7.1.1 postinstall: `node lib/install.js`
npm ERR! Exit status 1
npm ERR! 
npm ERR! Failed at the mozjpeg@7.1.1 postinstall script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
npm verb exit [ 1, true ]

yarn.lock中锁定了一个失效的地址，改用npm 不提示地址失效，直接来个 npm ERR! mozjpeg@7.1.1 postinstall: `node lib/install.js`  无法编译异常， 这个的根源还是这个 yarn.lock文件导致 编译mozjpeg的时候找不到依赖而编译失败， 而且神奇的是错误日志中居然没有任何和lock中锁定的失效地址registry.nlark.com 有关的信息......

所以，如果是 npm ERR! xxx postinstall: `node lib/install.js`  异常也可以尝试删除相关的 *.lock文件后再尝试看看，说不准就能解决你的问题。
