I have problem with log4js.
Problem is that when i ran node.sj error pops up:
Error: Cannot find module 'log4js'
at Function.Module._resolveFilename (module.js:336:15)
at Function.Module._load (module.js:278:25)

at Module.load (module.js:355:32)
at Function.Module._load (module.js:310:12)
at Function.Module.runMain (module.js:501:10)
So i instaled log4js with:
npm install log4js
And now the real error is here:
/home/bot/node_modules/log4js/lib/log4js.js:25
const debug = require('debug')('log4js:main');
^^^^^

Maybe i have broken bot. But bot should be OK.
I had this error in past but i fixed it and do not know how. (about 2years ago?) and error was in bot folder i think.
i have Debian 7 installed on server
Thx for response.
which version of node.js are you running?
node --version
First of all try to install your application packages with npm install log4j --save (to save it in your package.json).
It seems that you are using an old version of node.js!
Using this site you can see when the keyword const was introduced without requiring the strict keyword!
http://node.green/#ES2015-bindings-const
To fix the error just need to update your node.js to the latest stable version.
Another solutions: (The previous one is my favourite).
You can set a single specific file to be strict by writing 'use strict' on top of your file.
Or you can force to run your whole application to strict by using node --use_strict index.js (I wont recommend this one)

I have installed express globally and also ran npm update -g and I can create express app using terminal without problems. But when I create a new nodejs project in Netbeans 8.2 I get these errors :
module.js:472
throw err;

Can someone help me integrate Expressjs properly with netbeans please? Thanks in advance.
[UPDATE]
I figured there is something wrong in the Node path in Netbeans. Can someone tell me what do I add here for Ubuntu :
I made this app 1-2 years ago, and I was new to node so I didn't make a proper package.json file when it was created. for some reason, it's not running any more. here is the error when i try to run server.js.

it looks like the bindings module is from the osc-min folder. i tried to go in there and run an npm install but no luck. i put everything on the github
I haven't found any posts that have an answer for this one. It appears to be a sourcing issue, but no matter what I try I can't seem to source it properly. I get the following error when trying to launch my application.
is-buffer is installed. I see it in my node-modules directory.
C:\MY-APP\dataService>node dataAPI.js
module.js:338

I tried setting this in my binary file as well as my package.json. I'm able to change it in my binary file, but no matter what I'm not able to find the correct src dir.
I also tried npm install is-buffer -g to no avail. Any advice?
Unexpected token ILLEGAL
I was able to update the source to
var isBuf = require('C:\VF_PDO_APP\node_modules\is-buffer');
So now it seems to be going to the right place I think. Now however, I'm getting Unexpected token ILLEGAL.

You first must install all your project dependencies, do it on the root folder of your project:
npm install
For your problem with socket.io try to:
npm install socket.io --save
For the bson problem:
npm install bson --save
(for this one probably you will need to install python and c++)
I'm trying to use 'scrypt' module. The problem is that when I try to run my nodejs application (node app.js), I get this error:

Module._extensions[extension](this, filename);

I installed 'scrypt' module with this line:
npm install scrypt -msvs_version=2012
the -msvs_version is taken from this answer
You should have a look at this node-scrypt issue.
According to what is said there, you should be able to solve your problem by
either installing OpenSSL for Windows
or installing and building with Visual Studio 2010

Recently cloudfoundry made some changes for Node.js modules support. Have a look at here http://blog.cloudfoundry.com/2012/12/19/recent-changes-in-node-js-modules-support/
You have probably installed the module globally, which is fine for local development but you need to deploy the application with the module.
Before deploying via vmc, run npm install in the project directory.
