[SOLVED] Adafruit_DHT not working for python 3 Raspberry Pi 3 B

Issue

This is what i did:

git clone https://github.com/adafruit/Adafruit_Python_DHT.git

cd Adafruit_Python_DHT

sudo apt-get install build-essential python-dev

sudo python setup.py install

This^ was given in the github link itself. I did this and my code worked perfectly with DHT11 sensor in python 2.x but its failing with python 3. The error that I'm getting is:

RuntimeError: Error accessing GPTO. Make sure program is run as root with sudo!

My code is:

import Adafruit_DHT
import time

while True:
    time.sleep(1)
    humidity, temperature = Adafruit_DHT.read_retry(Adafruit_DHT.DHT11,4)
    print(temperature)
    print(humidity)

Works perfectly well with python 2, the issue is with python 3. I'm using a Raspberry Pi3 B for the GPIO interface.

Edit: I tried sudo python temper.py and it works again, but sudo python3 temper.py still doesn't work, with one small change, it doesn't give any errors but now the output is

None
None
None
None

basically, 'None' appears in place of the sensor value for Temperature and Humidity.

Solution

Since you are using Python 3 please install the library using the right command:

sudo python3 setup.py install
