Python Question

ImportError: cannot import name Pubnub

I am trying to control an LED on my Raspberry Pi with the Pubnub platform.
I just started and I tried this tutorial:

https://www.pubnub.com/blog/2015-05-27-internet-of-things-101-getting-started-w-raspberry-pi/

However, when I want to execute a Python file that imports the Pubnub library with the following line:

from pubnub import Pubnub


I get this error message:

ImportError: cannot import name Pubnub


I did everything exactly as told in the tutorial. I even copied the .py classes from their Github repository.

This is my class:

import RPi.GPIO as GPIO
import time
import sys
from pubnub import Pubnub

GPIO.setmode (GPIO.BCM)

LED_PIN = 17

GPIO.setup(LED_PIN,GPIO.OUT)

pubnub = Pubnub(publish_key='xxxx', subscribe_key='xxxx')

channel = 'disco'

def _callback(m, channel):
print(m)
if m['led'] == 1:
for i in range(6):
GPIO.output(LED_PIN,True)
time.sleep(0.5)
GPIO.output(LED_PIN,False)
time.sleep(0.5)
print('blink')

def _error(m):
print(m)

pubnub.subscribe(channels=channel, callback=_callback, error=_error)

Answer

try:

pip install pubnub

I did it and it works fine. No need to github anything. pip is available for Linux and Windows.
