request nodejs package not being found

Question

I install request package using npm. It appears to be located here: /usr/local/lib/node_modules/request/

var request = require("request");

request("http://www.google.com", function(error, response, body) {
  console.log(body);
});

module.js:340 throw err; ^ Error: Cannot find module 'request'...

What do I need to alter or perform? Further info, MAC OSX, node-v0.10.26.pkg, sudo -H npm install -g request, no errors

Answer 1

I think you have installed the package using the -g flag (global).
That's not how you should have installed the package.

To fix your problem, install the package locally:

npm install request

Or use a package.json file to persist the dependency:

{
  "name": "test",
  "version": "0.1.0",
  "dependencies": {
    "request": "*"
  }
}

Answer 2

You need to install the package in your project directory, not globally. So run npm install from your project directory without the -g flag.

Answer 3

Use advice by @Florent. Your direct problem, however, is that the global location is not known to node. If you still want to enable it, set the value of NODE_PATH to /usr/local/lib/node_modules (on Mac OS X in /etc/launchd.conf to make it available to all on boot).
