安装nodejs npm npx时遇到的问题：
环境：Ubuntu22.04
我从nodejs官网上下载的Linux包，解压tar包后，里面有npm npx node 4个可执行文件，运行了./npm -V，出现了如下错误：
ERROR: npm v9.5.1 is known not to run on Node.js v8.17.0. You'll need to upgrade
to a newer Node.js version in order to use this version of npm. This version of
npm supports the following node versions: `^14.17.0 || ^16.13.0 || >=18.0.0`. You
can find the latest version at https://nodejs.org/.

这个问题卡了有3天左右了，恳请前驱们能够指导下
