執行下面命令,安裝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
遇到如下報錯
ubuntu@ubuntu22:~$ sudo apt-get install nodejs -y Reading package lists... Done Building dependency tree... Done Reading state information...

這個錯誤表明在安裝 Node.js 18 時，出現了檔案衝突問題，特別是 node.stp 檔案被兩個不同的包（nodejs 和 libnode72）包含。解決這個問題的辦法通常是先解除安裝衝突的舊版本，再安裝新的 Node.js 版本
解決步驟
ubuntu@ubuntu22:~$ sudo apt-get remove libnode72
ubuntu@ubuntu22:~$ sudo apt autoremove
ubuntu@ubuntu22:~$ sudo apt install -y nodejs
指令碼內容如下:
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);
執行指令碼獲得新的html檔案:
ubuntu@ubuntu22:~$ nodejs update_html.js > new.html
