ModuleNotFoundError: No module name 'requests'

Hi,

I have a problem when I try to run python3 main.py.
I followed your installation guide and adjusted the paths (since I don't use a RPi) in both main.py and KlipperLCD.service to fit my setup:

main.py

class KlipperLCD ():
    def __init__(self):
        self.lcd = LCD("/dev/serial/by-path/pci-0000:00:10.0-usb-0:3:1.0-port0", callback=self.lcd_callback)
        self.lcd.start()
        self.printer = PrinterData('XXXXXX', URL=("127.0.0.1"), klippy_sock='/home/db/printer_1_data/comms/klippy.sock', callback=self.printer_callback)

KlipperLCD.service

[Unit]
 Description=KlipperLCD Service
 After=moonraker.service

[Service]
 Type=simple
 User=db
 Restart=always
 RestartSec=1
 ExecStart=/bin/sh -c '/usr/bin/env python3 /home/db/KlipperLCD/main.py  > /tmp/KlipperLCD.log 2>&1'

[Install]
 WantedBy=multi-user.target

When executing python3 main.py in ~/KlipperLCD it gives me the following error though:

Traceback (moste recent call last):
    File "/home/db/KlipperLCD/main.py", line 8, in <module> from printer import PrinterData
    File "/home/db/KlipperLCD/printer.py", line 7, in <module> import requests
ModuleNotFoundError: No module named 'requests'

Do you have an idea what's wrong? TIA

You are missing the requests module run "pip3 install requests" if you see "No module named 'example'" it usually means your missing a dependency, if you run into the issue "no module named 'PIL'" you'll also need to "pip3 install pillow". Please feel free to reach out with any other issues :)

Thanks for the answer! I'll give it a try in a few minutes :) That's odd tho, I followed the installation instructions, but it's probably due to the distro I'm using? Running latest Lubuntu on the HP T630..

Ha, it worked! Thank you so much!

It seems to work - I didn't try while printing yet, just did some basic checks and I'll have to do some further testing about the functionality, so I'll close this issue for now. What I can already say tho is that the printer's name doesn't fit (it says "Elegoo Neptune 3 Pro"), some infos in the "About Machine" don't fit and some functions in the "Settings" menu don't work (e.g. Fan Control on/off which I assume is the part cooling fan?), but maybe there's a way to fix that as well. Especially for a multiple printer setup it would be nice to have the correct names then, maybe there could be sth like a config file for KlipperLCD where one can then add the necessary info or so?
