Question

var express = require('express')
, signup = require('./routes/signup')
,login=require('./routes/login')  
, http = require('http')
, path = require('path')
, cal=require('./routes/calculate')
, db = require('./routes/db')

, ejs = require('ejs')
, moment = require('moment')
, mysql = require('mysql');
var pool  = require('pooling');

var app = express();
pool.initializepool(10);


// all environments
 app.set('port', process.env.PORT || 3000);
 app.set('views', path.join(__dirname, 'views'));
 app.set('view engine', 'ejs');

当app.js中提到这个时，var pool不会抛出错误。但是当在更平滑的节点js文件中提到相同的行时，它会抛出错误，指出无法找到模块“池化”。这是我的db.js文件

 var mysql = require('mysql');
 var pool  = require('pooling');
 exports.validate= function(callback,email,password)
{
var connection=pool.getConnection();
var connection=connect();
  }

请帮忙

Answer 1

确保池有一个module.exports（它必须有bcoz才能在app.js中获取它）

然后确保相对路径正确，如＆＃34; ./ routes / login＆＃34;

希望这有帮助

print(info["set1"]![2])

快递js中的require语句会抛出错误
