C:\Users\Basel\Desktop\Todo List>

Why this application won't start up? I've already tried a global npm install.

Solution 1

In ./models/todo, the period indicates that node will look in the same folder that api.js is in, which would look for \Todo List\routes\models\todo.js. This does not start from the root of the application. To require this, you'll need to us two periods to jump up a level, and specify the app path as well:

var todo = require('../app/models/todo');

Solution 2

maybe you did not set the system value : NODE_PATH; it should point to your global module location;

in Linux: export NODE_PATH=/usr/local/lib/node_modules/ works good for me;

You need to provide more details. Do you have a todo.js file in the models directory that's at the same level as the file that's calling require?

So is it in the location \Todo List\app\models\todo.js?

[Suhayb]

in my case node parses ../ as it is in var todo = require('../app/models/todo'); so output would be ../app/models/todo not parent/app/models/todo!
