錯誤“MODULE NOT FOUND”,找不到模組

我正在嘗試解決路徑問題:

這就是我的文件結構: /www/html/

  1. databaseConnection.js
  1. LoginPageScript.js

在資料庫js檔案中,如下程式碼:

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 };

我假設匯出池模組

現在我正在嘗試將池匯入到另一個腳本中,在本例中為 LoginPageScript.js,使用:

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

但是拋出的錯誤是:

Cannot find module '../database/databaseConnection'

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

我嘗試嘗試不同的路徑,例如:

  1. /database/databaseConnection.js
  2. #./database/databaseConnection.js

#../database/databaseConnection.js########### ### ###似乎沒有一個起作用###

    嘗試透過點註解遍歷 databaseConnection.js 檔案。

    並嘗試使用:

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