Program Running Pika Throwing AMQPConnectionError

Question

Going through the Rabbit MQ Pika HelloWorld tutorial found here: https://www.rabbitmq.com/tutorials/tutorial-one-python.html

The problem is, I keep getting this error whenever I run my receive script:

Traceback (most recent call last):
  File "receive.py", line 5, in <module>
    pika.ConnectionParameters(host='localhost'))

  File "C:\Users\Colin Warn\PycharmProjects\untitled2\venv\lib\site-packages\pika\adapters\blocking_connection.py", line 360, in __init__
    self._impl = self._create_connection(parameters, _impl_class)

  File "C:\Users\Colin Warn\PycharmProjects\untitled2\venv\lib\site-packages\pika\adapters\blocking_connection.py", line 451, in _create_connection
 
raise self._reap_last_connection_workflow_error(error)

pika.exceptions.AMQPConnectionError

Here's the code I'm attempting to run:

#!/usr/bin/env python
import pika

connection = pika.BlockingConnection(
    pika.ConnectionParameters(host='localhost'))
channel = connection.channel()

channel.queue_declare(queue='hello')


def callback(ch, method, properties, body):
    print(" [x] Received %r" % body)


channel.basic_consume(
    queue='hello', on_message_callback=callback, auto_ack=True)

print(' [*] Waiting for messages. To exit press CTRL+C')
channel.start_consuming()

Any help is much appreciated. Thank you so much in advance.

All you need to do is installing RabbitMQ in your PC. You can simply run with docker using the command below in another terminal, and re-run your code

docker run -it --rm --name rabbitmq -p 5672:5672 -p 15672:15672 rabbitmq:3-management

You need to install RabbitMQ on your machine: https://rabbitmq.com/download.html

After installing RabbitMQ server re-run the script.
