Can't import name "Dispatcher" from telegram.ext-CodePudding

I am a beginner with python-telegram-bot, I have installed version 20.0.

I installed a package "django-telegram bot" to help me integrate python-telegram-bot into django but I got an import error upon running the code

ImportError: cannot import name "Dispatcher" from telegram.ext

I delved into the python-telegram-bot package and discovered that there is no module called Dispatcher, but several online tutorials directly imported Dispatcher from telegram.ext.

To import the dispatcher module, you'll first need to install the python-telegram-bot package. It looks like, from the question you have done this.

pip install python-telegram-bot

then all you have to do is this:

from telegram import Dispatcher

it is not imported from telegram.ext. from what i can see the telegram.ext part looks like this.

from telegram.ext import MessageHandler, Filters

def handle_message(bot, update):
    message = update.message.text
    bot.send_message(chat_id=update.message.chat_id, text=message)

dp.add_handler(MessageHandler(Filters.text, handle_message))

and that reqires a bot which is derived from this:

from telegram import Bot
bot = Bot(token="YOUR_BOT_TOKEN")

Which is different to what is suggested in the original question.

CodePudding user response：

The django-telegram-bot library is just not compatible with version 20 of python-telegram-bot. As you can see in the requirements file it requires the ancient version 5.3.0 of python-telegram-bot (it was released on 2016-12-11).
