node . and npm start don't work

The title says most of the problem. When I try to run node . I get:

    module.js:340
    throw err;
          ^
Error: Cannot find module 'static-favicon'
    at Function.Module._resolveFilename (module.js:338:15)
    at Function.Module._load (module.js:280:25)
    at Function.Module.runMain (module.js:497:10)
    at startup (node.js:119:16)
    at node.js:902:3

There seems to be no modules folder actually. I'm just running express in an empty directory

npm works fine however. This is with a fresh express install if it matters. Any help would be awesome, thanks!

the full error messages:

I had the same issue after running the express-generator on a non-empty directory with some node modules already installed in node_modules, especially express itself. Simply nuke the folder, reinstall all your dependencies and you should be good to go:

rm -rf ./node_modules
npm install
npm start

EDIT: Tuns out that at some stage in the process I had installed serve-favicon and saved that to the local package.json. Looks like the express generator failed to add that dependency. Therefore:

npm install serve-favicon --save
npm start

Do npmstart which installs all the required modules for your project

Use serve-favicon instead of static-favicon. Also verify that you have serve-favicon installed correctly. Do cd serve-favicon, check package.json, and then run npm install to have all dependencies installed correctly.

After using the express-generator to generate the node application, you need to install the dependencies for the project. This is done via:

$ npm install

Once this is done, you can start the app using npm:

$ npm start

By default, the express generated apps state this as the start command for npm (you can view this in the package.json file):

"start": "node ./bin/www"

So to execute the same thing via the command line, you would run:

$ node ./bin/www

given a dir tree like:

myapp
 - lib
  - favicon.ico
 - app.js
 - package.json
 - node_modules (npm installs all modules in here)

if you are trying to access favicon.ico in your app.js

var express = require('express'),
    fs = require('fs'); // this is for reading static files 

var favicon = require(fs.readFileSync('./lib/favicon.ico'));

the var for favicon may not be what you expect. The best way for serving static files would be to set up a static directory with a route so anyone hitting that route with a param gets that files: for example:

https://mynodeapp.com/static/images/{param}

where param would be the name of the file (this is an example using Hapi - express has something similiar for serving static files)
