执行下面命令,安装nodejs 和 npm
ubuntu@ubuntu22:~$ sudo apt update
ubuntu@ubuntu22:~$ sudo apt install npm # npm 是 Node.js 的包管理工具
ubuntu@ubuntu22:~$ sudo apt install -y curl
ubuntu@ubuntu22:~$ curl -fsSL https://deb.nodesource.com/setup_18.x | sudo -E bash -
ubuntu@ubuntu22:~$ sudo apt install -y nodejs
遇到如下报错

这个错误表明在安装 Node.js 18 时，出现了文件冲突问题，特别是 node.stp 文件被两个不同的包（nodejs 和 libnode72）包含。解决这个问题的办法通常是先卸载冲突的旧版本，再安装新的 Node.js 版本
解决步骤
ubuntu@ubuntu22:~$ sudo apt-get remove libnode72
ubuntu@ubuntu22:~$ sudo apt autoremove
ubuntu@ubuntu22:~$ sudo apt install -y nodejs
脚本内容如下:
ubuntu@ubuntu22:~$ cat update_html.js
const juice = require('juice');
const fs = require('fs');
const html = fs.readFileSync('file.html', 'utf8');
const inlinedHtml = juice(html);
console.log(inlinedHtml);
执行脚本获得新的html文件:
ubuntu@ubuntu22:~$ nodejs update_html.js > new.html
