ModuleNotFoundError: No module named 'paho.mqtt.Client'

import paho.mqtt. client as mqtt

mqttc = mqtt.Client()
导入client用小写的时候报错让用大写，用大写报错找不到该模块

Traceback (most recent call last):
  File "C:\Users\38933\Desktop\订阅消息虚拟数据.py", line 13, in <module>
    client = mqtt.client("stu215150331")
AttributeError: module 'paho.mqtt.client' has no attribute 'client'. Did you mean: 'Client'?

ModuleNotFoundError: No module named 'paho.mqtt.Client'

第一次报错是表示你导入的模块mqtt里面找不到client，即mqtt.client是找不到的，它提示你是不是client要改为Client
可能的改法：

import paho.mqtt.client as mgtt
mqttc = mgtt.Client()
