Error: Cannot find module 'mqtt' but it is installed

[static sky]

Heyho, see picture.
mqtt is installed, i checked via ``npm list-g`. Why do i run into this error the whole time?
Thanks

root@raspberrypi:/home/pi# npm list -g
/usr/local/lib
├── corepack@0.17.0
├── mqtt@4.3.7
├── n@2.1.12
├── node-gyp@3.7.0
├── node-red@3.0.2
└── npm@9.6.5

I also did npm install in the mqtt package folder

Im so confused

If u ask what code the furkan.js is, it is this ```js
const mqtt = require('mqtt')
const client = mqtt.connect('mqtt://test.mosquitto.org')

client.on('connect', function () {
client.subscribe('presence', function (err) {
if (!err) {
client.publish('presence', 'Hello mqtt')
}
})
})

client.on('message', function (topic, message) {
// message is Buffer
console.log(message.toString())
client.end()
})

It is just an example code to test if its working

And for some fking reason it says mqtt module not found but its clearly installed??

why is it installed globally though?

that probably isn't the issue but it should be installed locally to the project

I tried both ways, lots of articles say do globally

not global woul be just without -g i guess?

[woven sage]

yes

what defines a "project"

sorry im new to js and node

I just have this file i want to make run

but as u said it shouldnt be the issue anyway

[woven sage]

the package's readme says to install it locally

[static sky]

do i just run npm install mqtt in the same folder where the .js file is?

[woven sage]

a project is a directory which holds your package.json and node_modules and whatever source and asset files you may have, ie basically your entire project is there

it's created automatically if you do npm install locally or if you do npm init

omfg

that was it

i wasted too much time on this

[woven sage]

i mean, you could, but i don't think you're supposed to have projects in /usr/local/bin
