Paho-MQTT with Python3.8 throwing error: AttributeError: module 'socks' has no attribute 'HTTP'

Hi Pythonanywhere fellows,

I'd like to subscribe to a TheThingsNetwork topic using the MQTT API: https://www.thethingsindustries.com/docs/integrations/mqtt/

The Api works fine for me using the paho-mqtt client: https://pypi.org/project/paho-mqtt/ My code looks as follows:

import context
import paho.mqtt.subscribe as subscribe
import time
import re
import json

while True:
    m = subscribe.simple(topics=['#'], hostname="eu1.cloud.thethings.network", port=1883, auth={'username':"mycrazyusername@ttn",'password':"mycrazypw"}, msg_count=2)
    for a in m:
        payload = json.loads(a.payload)
        print(payload)

I am receiving following error that relates to the socks module:

Do you have any ideas how to fix that?

Update: I've tested the command with python 3.6 and receive exactly the same error.

I suspect this may be an issue that is because of something that we have pre-installed. There are a lot of packages that provide the socks module and I could not find out which one paho-mqtt needs. Try using a virtualenv, so that you are not interacting with the pre-installed packages and see if that helps.
