Error: Cannot find module 'debug'

I have been trying on a raspberry pi zero (wired usb to rj45 which I use to ssh into it and the wireless for tuya-convert) with the both the lite raspbian and full raspbian, and no matter what I do, it doesn’t want to connect.

Looking at the smartconfig log file, I see this

pi@raspberrypi:~/tuya-convert/scripts $ cat smarthack-smartconfig.log 
module.js:559
    throw err;
    ^

Error: Cannot find module 'debug'

    at Module.load (module.js:575:32)
    at tryModuleLoad (module.js:515:12)
    at Function.Module._load (module.js:507:3)

I used a fresh install of the OS, then ran these commands, before I started with tuya-convert

sudo apt-get update sudo apt-get dist-upgrade sudo apt-get install network-manager sudo apt install git

Any ideas what I can try to make this work?

Also here is my smarthack web file

pi@raspberrypi:~/tuya-convert/scripts $ cat smarthack-web.log

I was previously having success but for the last few days can’t get any sonoff devices to connect to vtrust-flash to start the process. My phone connects to it, but the sonoff devices (bulb, switch) just flash in pairing mode until timing out. I noticed this same "cannot find module ‘debug’ error so I ran npm -i inside scripts/smartconfig as suggested. That seemed fine except for two warnings:

npm WARN deprecated circular-json@0.3.3: CircularJSON is in maintenance only, flatted is its successor.
npm WARN tuya-helper@1.0.0 No repository field.

Running start_flash.sh I now get this:

This is on an ubuntu 16.04 server machine.

UPDATE Success by using the python version mentioned above. To get that to work it was necessary to also do: apt-get install python3-crypto

I gave up on my raspberry pi zero w, and used a laptop to flash my switches, so I am good now. Thanks for your help
