Question

import os
from telegram.ext import Updater, CommandHandler, MessageHandler, filters

def start(update, context):
    context.bot.send_message(chat_id=update.effective_chat.id, text="test")

def echo(update, context):
    context.bot.forward_message(chat_id=ADMIN_CHAT_ID, from_chat_id=update.message.chat_id, message_id=update.message.message_id)
    context.bot.send_message(chat_id=update.effective_chat.id, text="test")
    ADMIN_CHAT_ID = os.environ.get('1014171853')

def main():
    TOKEN = os.environ.get('<MY-TOKEN>')
    ADMIN_CHAT_ID = os.environ.get('228')

    token= "<MY-TOKEN>"
    updater = Updater(token, use_context=True)
    dispatcher = updater.dispatcher

    start_handler = CommandHandler('start', start)
    echo_handler = MessageHandler(filters.text & ~filters.command, echo)

    dispatcher.add_handler(start_handler)
    dispatcher.add_handler(echo_handler)

    updater.start_polling()
    updater.idle()

if __name__ == '__main__':
    main()

              ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: Updater.__init__() got an unexpected keyword argument 'use_context'

当我收到此错误时，我尝试将令牌指定为变量，但我仍然不明白如何修复此错误。我的 python-telegram-bot 版本是 20.2
