我正在尝试解决路径问题：

这就是我的文件结构： /www/html/

• /数据库/

1. databaseConnection.js

• /脚本/

1. LoginPageScript.js

• 服务器.js
• index.html

在数据库js文件中，如下代码：

const mysql = require('mysql2');

const pool = mysql.createPool({
  connectionLimit: 10,
  host: process.env.DB_HOST,
  port: process.env.DB_PORT,
  user: process.env.DB_USER,
  password: process.env.DB_PASSWORD,
  database: process.env.DATABASE
});


pool.getConnection((err, connection) => {
  if (err) {
    console.error('Error connetcting to database: ', err);
    return;
  }
  console.log('Connection to database succefully established!');
});

module.exports = { pool };

我假设导出池模块

现在我正在尝试将池导入到另一个脚本中，在本例中为 LoginPageScript.js，使用：

const { pool } = require('../database/databaseConnection.js');

但是抛出的错误是：

Cannot find module '../database/databaseConnection'

  requireStack: [
    '/var/www/html/scripts/LoginPageScript.js',
    '/var/www/html/server.js'
  ]
}

我尝试尝试不同的路径，例如：

1. /database/databaseConnection.js
2. ./database/databaseConnection.js
3. ../database/databaseConnection.js

似乎没有一个起作用
