Cannot find module mysql - error

Question

I have installed nodejs and mysql(also the work bench)

I am building a server using nodejs and mysql.

in my code I write:

var mysql = require('mysql');
var TEST_DATABASE = 'nodejs_mysql_test';
var TEST_TABLE = 'test';
var client = mysql.createClient({
  user: 'root',
  password: 'root',
});

client.query('CREATE DATABASE '+TEST_DATABASE, function(err) {
  if (err && err.number != mysql.ERROR_DB_CREATE_EXISTS) {
    throw err;
  }
});

and the compiler gives me an error:

Error: cannot find module 'mysql'

Answer 1

This happens when you don't have the module installed, so go to the root of your project and install node-mysql:

npm install mysql

You don't need to manually copy the folder yourself, dependencies are best handled with NPM.

Answer 2

i think that i solved it.

there is a folder node_modules under the nodejs folder in that folder there is a mysql folder. copied it to the folder that from there i am running my program, and i t works:)
