Question

我在python中创建了一个与DialogFlow通信的简单电报机器人。这是代码

#!/usr/bin/env python
from telegram.ext import Updater, CommandHandler, MessageHandler, Filters
import apiai, json
updater = Updater (token = '')
dispatcher = updater.dispatcher
# Processing commands
def startCommand (bot, update):
    bot.send_message (chat_id = update.message.chat_id, text = '')
def textMessage (bot, update):
    request = apiai.ApiAI (''). text_request()
request.lang = 'it'
request.session_id = 'TestBot'
request.query = update.message.text
responseJson = json.loads ( request.getresponse (). read (). decode ('utf-8'))
response = responseJson ['result'] ['fulfillment'] ['speech']

if response:
    bot.send_message (chat_id = update.message.chat_id, text = response)
else:
    bot.send_message (chat_id = update.message.chat_id, text = '')

start_command_handler = CommandHandler ('start', startCommand)
text_message_handler = MessageHandler (Filters.text, textMessage)

dispatcher.add_handler (start_command_handler)
dispatcher.add_handler (text_message_handler)

updater.start_polling (clean = True)

updater.idle ()

当我尝试启动它时，出现此错误

我已经以这种方式安装了pip

sudo apt-get install python-pip

此：*args: Any是仅Python3的语法。您已经安装了tornado的最新版本，该版本仅支持Python 3+。对于Python 2.7，您需要降级：

pip install -U tornado==5.1.1

5.1.1是当前支持Python 2.7的最新版本。
