I am new to node.js and stuck on the following. Any help will be appreciated:
I am running node.js (0.10.28) on ubuntu (12.10). The code I am working on is:
"use strict";
var mysql = require('node-mysql'),
connection = mysql.createConnection({
host: "127.0.0.1",
user: "user",
password: "password",
database: "dbname"
});
if(connection) {
console.log("Query");
connection.query("select * from client",function(err,res) {
if(err)console.log(err);
console.log(res);
});
}
I get the following error
Error: Cannot find module 'readable-stream'

I got this error for the a long while. Stupidly I hadn't installed gulp... In short this problem occurs when a package is missing.
npm install gulp -g
I would suggest working out which task you are running and then install that.
In my case, (windows)
after uninstalling nodejs, and before reinstalling it
I had to delete the folder:
C:\Program Files\nodejs\node_modules\npm
and after reinstalling node it worked like a sharm
There were many reason for this issue: I have faced this issue because I had older version of node.js related files.
Un-install the node.js
Go to your user folder like C:\Users\<uname> and find all the node.js related files and delete everything.
Install node.js freshly
It worked for me.
I was having this problem building a vue library. Deleting node_modules and re-running npm isntall and then rebuilding my lib worked.
After grepping I found:
$ cd /usr/lib/
$ ack-grep readable-stream
nodejs/sha/index.js
3:var Transform = require('stream').Transform || require('readable-stream').Transform
and change that line to:
var Transform = require('stream').Transform // || require('readable-stream').Transform
and error goes out!

I recently updated my operating system, which is Pop-OS, which is a Ubuntu's distribution. Before updating, I could run nodejs with ZeroMQ perfectly. Now, I can't run any file with ZeroMQ, not even with just this SLOC-line: const zmq = require('zeromq')
I am using Visual Studio code and also I tried to uninstall and install from scratch nodejs and npm and nothing works.
This is the error:
myuser#pop-os:~/Documents/Lab/fuentes$ node publicadorServer.js

throw err;

}
I have installed ZeroMQ with this command at the directory of the project : npm install zeromq#5
Any help would be appreciated.
Finally I could fix it, only with the command npm rebuild.
Unbelievable. I guess, installing a new version of node and the new operating system version make necessary to rebuild it, but I still don't understand that, if I uninstall nodejs and npm, why it was not working. Fortunately, it's all fixed.
I am trying to create & rum meteor app on win 8.1 pc

=> Your application has errors. Waiting for file change.
I search over the but didn't find specific result for windows.
As the latest version got this problem, use previous version to create a sample app like this,
meteor create --release 1.2.1 test-app
cd test-app
meteor
found on : https://github.com/meteor/meteor/issues/6609
Based on answers from this issue https://github.com/meteor/meteor/issues/6609 you need to :
Go to "C:\Users\username\AppData\Local.meteor\packages"
Move the packages causing the issue to another folder as you won't be able to delete them on windows due to long file names (templating, templating-tools, ecmascript, standard-minifier-css)
once the file deleted you can run "meteor npm install" then "meteor"
I have tested and it works for me.
I just removed all packages (withaout meteor) from AppData\Local.meteor\packages and run my app again. Meteor downloaded all packeges and now it is working.
The following fix worked for me:
Uninstall meteor from Windows (Programs and Features).
Install meteor (https://www.meteor.com/install)
Create a new Project (https://www.meteor.com/tutorials/blaze/creating-an-app)
I was using meteor 0.8.x but recently tried to upgrade to 0.9.2. It works locally but I'm not having any luck with meteor bundle or meteor build
First I got this error

Things I've tried
Made sure live/bundle/programs/server/node_modules does not exist before starting.
ran npm install in live/bundle/programs/server as the README says to
Things I noticed. There's no bcrypt deps in live/bundle/programs/server/package.json. In 0.8.2 I had commands to install both fibers and bcrypt manually but apparently I don't need the fibers one anymore. It looks like I do need the bcrypt one but it's in a different location than it used to be.
I don't see anything in the docs about needing to go to /var/projects/myproject/live/bundle/programs/server/npm/npm-bcrypt and install bcrypt. I can manually delete it but am I doing something wrong?
Like I said I'm already installing it where 0.8.2 needed it in programs/server. Should I be manually installing in program/server/npm/npm-bcrypt? Should I add that to my list of places to ignore
I put that in just to try it and so now I get this error
/var/projects/myproject/live/bundle/programs/server/node_modules/fibers/future.js:173
throw(ex);

Is that yet another module I need to manually install? I'm getting the impression I'm just doing something fundamentally wrong.
I've got the following meteor packages

# 'meteor add' and 'meteor remove' will edit this file for you,
# but you can also edit it by hand.

I had similar problems - I posted my solution over on DO

UPDATE - Here is the answer from that forum:
If anyone else has an issue like this with bcrypt - the app probably has its own copy in
/home/yourapp/bundle/programs/server/npm/npm-bcrypt/node_modules/bcrypt/
delete that noise. Then do this.
cd /home/yourapp/bundle/programs/server
npm install bcrypt
Then
cp -r /home/yourapp/bundle/programs/server/node_modules/bcrypt /home/yourapp/bundle/programs/server/npm/npm-bcrypt/node_modules/bcrypt/
then start your app and enjoy the meteory goodness.
On the general problem of . . .
(for those stumbling here via Google)
Cannot find module 'MODULE-NAME'
or
Can't find npm module 'MODULE-NAME'
If you've recently added or removed packages while the application is running, try stopping and restarting your meteor application.
// stop ( "CTRL+C" in terminal that launched process )
$ kill `ps ax | grep '[m]eteor' | awk '{print $1}'`
// start
$ meteor

Need to do parsing xml-file using Node.js.
Using a library for parsing xml2js.
Xml2js installed using the command "npm install xml2js".
However, if you run the code:
var fs = require ('fs'), xml2js = require ('xml2js');
var parser = new xml2js.Parser ();
fs.readFile ('<path to the xml-file>', function (err, data) {
parser.parseString (data, function (err, result) {
console.dir (result);
console.log ('Done');
});
});

Tell me, please, how to solve the problem?
I was also facing the same issue. Here's what I did:
Install the module using following:
$ npm install -g *module_name*
Then go to any parent dir of your project dir (it can be project dir itself) and run the following command:
$ npm link *module_name*
Make sure that the directory ./node_modules/xml2js exists.
When you run npm install somemodule at D:/test, it will be stored to D:/test/node_modules/somemodule, then you can require this module in D:/test/*.js, and you can not require it at D:/other/place/*.js. If you hope the module can be required anywhere you should run:
npm install somemodule -g
I had a similar issue and even tried the fix mentioned by Lellansin, but it didnt help. There were some issues with npm cache and I had to clear it using the command:
npm cache clean
And it worked for me.

Inside your app you obviously require the express module, probably like this:
var express = require('express');
For this line to work you need to install Express into the local context of your application. To do so run
$ npm install express
inside your application's folder. This will (if it does not yet exist) create a folder node_modules where all your dependencies go.
Additionally, I'd suggest that you put Express into your package.json inside the dependencies block, such as:
"dependencies": {
"express": "3.1.0"
}
Of course, you can adjust the version number to whatever version you use. Once you've done this for all of your dependencies, you can install them at once by simply running
$ npm install
That should fix it.
PS: It does not matter for this scenario whether you installed Express globally or not. A global installation is only good for having the express bootstrapper available system-wide. The require function always only searches within the local application context.
