Question

我正在从here重新创建基本的电报机器人示例，但是我遇到了一个小问题。

import logging
from telegram.ext import Updater, CommandHandler, MessageHandler, Filters
# Enable logging
logging.basicConfig(format='%(asctime)s - %(name)s - %(levelname)s - %(message)s',level=logging.INFO)
logger = logging.getLogger(__name__)
# Define a few command handlers. These usually take the two arguments bot and
# update. Error handlers also receive the raised TelegramError object in error.
def start(update, context):
    """Send a message when the command /start is issued."""
    update.message.reply_text('Hi!')

def help(update, context):
    """Send a message when the command /help is issued."""
    update.message.reply_text('Help!')

def echo(update, context):
    """Echo the user message."""
    update.message.reply_text(update.message.text)

def error(update, context):
    """Log Errors caused by Updates."""
    logger.warning('Update "%s" caused error "%s"', update, context.error)

def main():
    """Start the bot."""
    # Create the Updater and pass it your bot's token.
    # Make sure to set use_context=True to use the new context based callbacks
    # Post version 12 this will no longer be necessary
    updater = Updater("YOUR TOKEN HERE",use_context=True)
    # Get the dispatcher to register handlers
    dp = updater.dispatcher
    # on different commands - answer in Telegram
    dp.add_handler(CommandHandler("start", start))
    dp.add_handler(CommandHandler("help", help))
    # on noncommand i.e message - echo the message on Telegram
    dp.add_handler(MessageHandler(Filters.text, echo))
    # log all errors
    dp.add_error_handler(error)
    # Start the Bot
    updater.start_polling()
    # Run the bot until you press Ctrl-C or the process receives SIGINT,
    # SIGTERM or SIGABRT. This should be used most of the time, since
    # start_polling() is non-blocking and will stop the bot gracefully.
    updater.idle()
if __name__ == '__main__':
    main()

执行脚本后出现以下错误：

$ python test1.py

Traceback (most recent call last):
  File "test1.py", line 64, in <module>
    main()
  File "test1.py", line 39, in main
    updater = Updater(TOKEN,use_context=True)
TypeError: __init__() got an unexpected keyword argument 'use_context'

Answer 1

use_context自python-telegram-bot版本12起可用。您可以通过pip show python-telegram-bot来找到已安装的版本。

最简单的解决方案是仅删除参数use_context，即替换

updater = Updater("YOUR TOKEN HERE",use_context=True)

使用

updater = Updater("YOUR TOKEN HERE")

Answer 2

该错误告诉您use_context不是Updater初始化程序的有效关键字参数。 Python Telegram Bot的第12版不再支持该参数。

我想您已经pip install python-telegram-bot==12.0.0b1 --upgrade安装了该库，并且正在安装版本12.0.0b1。

您可以通过运行以下命令来再次进行安装：

卸载当前版本的python-telegram-bot：pip uninstall python-telegram-bot
安装库的11版本：pip install python-telegram-bot==11

此外，如果您不想更改库版本并继续使用python-telegram-bot 12.0.0，则只需从Updater类的实例中删除use_context参数。

此行：

updater = Updater("YOUR TOKEN HERE",use_context=True)

将成为：

updater = Updater("YOUR TOKEN HERE")
