Python 3 Windows 安装出现包错误 ModuleNotFoundError

Question

I have recently started using Python and have installed version 3.7.3 on my Windows 10 machine running as administrator. I then ran the following command in a command prompt to install the xmpppy package

python -m pip install xmpppy

Next I created the following base.py file that uses the aforementioned xmpppy package

#!/usr/bin/env python 

import xmpp

user="user"
password="pword"
server="server"

jid = xmpp.JID(user) 
connection = xmpp.Client(server,debug=[]) 
connection.connect() 
result = connection.auth(jid.getNode(), password,"LFY-client") 

connection.sendInitPresence() 

while connection.Process(1): 
pass

Now when I run the command

python base.py

in the folder that the base.py file exists I get the following error message:

Traceback (most recent call last):
 File "base.py", line 3, in <module>
  import xmpp
 File "C:\Users\AGO109\AppData\Local\Programs\Python\Python37\lib\site-packages\xmpp\__init__.py", line 29, in <module>
import simplexml,protocol,debug,auth,transports,roster,dispatcher,features,browser,filetransfer,commands
ModuleNotFoundError: No module named 'simplexml'

In the folder C:\\Users\\AGO109\\AppData\\Local\\Programs\\Python\\Python37\\lib\\site-packages\\xmpp simplexml.py, protocol.py etc. all exist and the windows system variables contain the paths for python and packages, so what's the problem?

Answer 1

I'm facing same issue.

Try installing each of the packages using command like pip install simplexml and then run your code. Mine is stuck at installing transports .

Alternately,you may try switching to using sleekxmpp that comes bundled with your python installation. As sleekxmpp has latest version published in 2017 compared to that of 2006 for xmpppy , i'm planning to stick with using sleekxmpp library. If you update your code to use sleekxmpp as per the boilerplate code at https://pypi.org/project/sleekxmpp/ , XMPP connections work.
