No module named 'paho'

[prutsky]

Hi, Hi I installed paho (with sudo pip install paho-mqtt) but still I get the following error:

$ python3 Northcliff_AQI_Monitor_Gen.py 
Traceback (most recent call last):
  File "Northcliff_AQI_Monitor_Gen.py", line 5, in <module>
    import paho.mqtt.client as mqtt
ModuleNotFoundError: No module named 'paho'

Why isn't paho found?

That's strange. Maybe try sudo pip3 install paho-mqtt

Thank you, that was it! But after installing "Adafruit_IO" and creating a config.json file I got stuck at the following error:

$ python3 Northcliff_AQI_Monitor_Gen.py

Do you need the mqtt messages enabled? If so, do you have an mqtt broker on your network and have you set up config.json to use that broker's name or IP address?

[roscoe81]

Sorry, I answered before looking at your retrieved config file. You can solve the problem by setting 'enable_indoor_outdoor_functionality’: false in your config.json file. You need an mqtt broker if it’s set to true so that the indoor and outdoor Enviro Monitors to communicate with each other.

I just want to say thank you! You really helps me!
