我有一个问题后，转移我的tg机器人到新的服务器。我不知道为什么我有错误。好像我丢失了一些Python包来安装。在旧服务器与操作系统的参数相同，我没有这个机器人的任何问题。
抱歉，我的错误太幼稚了。我试着谷歌我的错误，没有答案。
代码1：

def start(bot, update):
    if update.message.from_user.username == AAA:
        bot.sendMessage(chat_id=update.message.chat_id, text="Text_one")
    else:
        bot.sendMessage(chat_id=update.message.chat_id, text="Text_two")
...
updater = Updater(token=bot_token)

start_handler = CommandHandler('start', start)
updater.dispatcher.add_handler(start_handler)

错误1：

代码2：

def rating(bot, update):
    bot.send_sticker(chat_id,'some_sticker_id')
...
rating_handler = CommandHandler('rating', rating)
updater.dispatcher.add_handler(rating_handler)
