我正在尝试解决路径问题:
这就是我的文件结构: /www/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' 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' ] }
我尝试尝试不同的路径,例如:
似乎没有一个起作用
尝试通过点注释遍历
databaseConnection.js
文件。并尝试使用:
