Saya cuba menyelesaikan masalah laluan:
Ini adalah struktur fail saya: /www/html/
Dalam fail js pangkalan data, kod berikut:
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 };
Saya menganggap eksport modul pool
Sekarang saya cuba mengimport kumpulan ke dalam skrip lain, dalam kes ini LoginPageScript.js, menggunakan:
const { pool } = require('../database/databaseConnection.js');
Tetapi ralat yang dilemparkan ialah:
Cannot find module '../database/databaseConnection' Require stack: - /var/www/html/scripts/LoginPageScript.js - /var/www/html/server.js at Module._resolveFilename (node:internal/modules/cjs/loader:956:15) at Module._load (node:internal/modules/cjs/loader:804:27) at Module.require (node:internal/modules/cjs/loader:1022:19) at require (node:internal/modules/cjs/helpers:102:18) at Object.<anonymous> (/var/www/html/scripts/LoginPageScript.js:3:18) at Module._compile (node:internal/modules/cjs/loader:1120:14) at Module._extensions..js (node:internal/modules/cjs/loader:1174:10) at Module.load (node:internal/modules/cjs/loader:998:32) at Module._load (node:internal/modules/cjs/loader:839:12) at Module.require (node:internal/modules/cjs/loader:1022:19) { code: 'MODULE_NOT_FOUND', requireStack: [ '/var/www/html/scripts/LoginPageScript.js', '/var/www/html/server.js' ] }
Saya cuba mencuba jalan yang berbeza seperti:
Tiada satu pun daripada mereka nampaknya berfungsi

Cuba melintasi databaseConnection.js
fail melalui ulasan titik.
Dan cuba gunakan:
const { pool } = require('./database/databaseConnection.js');
