How to Solve Wechat wxpy Robot Error

Error message sent by wechat robot of higher version Python 3.9

lib\site-packages\itchat\”, line 69, in msg_formatter

d[k]  = htmlParser.unescape(d[k])

AttributeError: ‘HTMLParser’ object has no attribute ‘unescape’

Solution: modify the source code of the corresponding file

The principle is to modify the imported package from HTML import unescape

The modified code is:

import re, os, sys, subprocess, copy, traceback, logging

from html import unescape

import requests

from . import config

logger = logging.getLogger('itchat')

emojiRegex = re.compile(r'<span class="emoji emoji(.{1,10})"></span>')
