I have set a discord bot on glitch.com website but it's actually not finding discord.js

The error is :
^

I don't know how to make it find discord.js.
Thank you for answers !
Here are the files contained in the project

What about package? Did you added discord.js
from package.json?
if you don't know I'll try to explain : go to package.json and click to add packages and type discord.js to there. And click the first thing you see. I hope it works!

'weexpack run web' throwing error

I've installed a weexpack project.
When I am trying to run the command weexpack run web It's showing error.
module.js:442
throw err;

Can anyone help me with it?

As mentioned by #zahidul-islam-suzon in the comment above, it looks like this is a case sensitivity bug in weexpack: https://github.com/weexteam/weex-pack/issues/148#issuecomment-302861410
It can be fixed by renaming /usr/local/lib/node_modules/weexpack/src/run/web.js (or wherever your weexpack is installed) to Web.js.

I Have installed the below npm module
https://github.com/feross/simple-peer
by,
#sudo npm install simple-peer -g
But When tried including the module, it is unable to find the module. I received the below error
module.js:340
throw err;
^

Meteor + cordova-ios. Error: Cannot find module ‘./util.js’

Meteor 1.3.2.4.
I got this error everytime I try to meteor run / meteor run ios-device a project with cordova-ios.

Do you have any thoughts what can cause that issue?
UPDATE: This happens only on MAC, on WIN everything works.

Re-installing Meteor solved this issue.

node.js and node-postgres syntax error

I just installed node-postgres by running npm install pg .
In my source code, I added var pg = require('pg");
and when I run I now get
module.js:340
throw err;
^
Error: Cannot find module 'pg'

What step am I missing?

Where is the node_modules folder in relation to your application?
from http://nodejs.org/api/modules.html:
If the module identifier passed to require() is not a native module, and does not begin with '/', '../', or './', then node starts at the parent directory of the current module, and adds /node_modules, and attempts to load the module from that location.
