程序运行 Pika 抛出 AMQPConnectionError

Question

通过此处找到的 Rabbit MQ Pika HelloWorld 教程： https : //www.rabbitmq.com/tutorials/tutorial-one-python.html

问题是，每当我运行接收脚本时，我都会收到此错误：

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

这是我试图运行的代码：

#!/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()

任何帮助深表感谢。 非常感谢你提前。
