我正在嘗試解決路徑問題:
這就是我的文件結構: /www/html/
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' 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' ] }
我嘗試嘗試不同的路徑,例如:
P粉3024843662024-04-03 13:35:23
嘗試透過點註解遍歷 databaseConnection.js
檔案。
並嘗試使用:
const { pool } = require('./database/databaseConnection.js');
