I built a Telegram bot to fetch stock prices from Yahoo Finance but encountered an error saying ‘Updater’ is missing in telegram. How can I fix the issue?
hey mate, had the same issue. try uninstalling and reinstalling the library. use ‘pip uninstall python-telegram-bot’ then ‘pip install python-telegram-bot’. if that doesnt work, check ur code for any outdated imports. good luck!
I ran into this problem a while back when updating my crypto price alert bot. The issue stems from changes in the python-telegram-bot library’s structure. To resolve it, you’ll need to modify your code to use the new Application class instead of Updater.
First, update the library with ‘pip install python-telegram-bot --upgrade’. Then, replace your Updater initialization with something like:
from telegram.ext import Application
app = Application.builder().token(‘YOUR_BOT_TOKEN’).build()
You’ll also need to adjust how you set up handlers and start the bot. The official docs have a migration guide that’s pretty helpful for making these changes. It took me a bit of time to refactor everything, but the new structure actually made my bot more efficient in the long run.
It appears that you’re using an older example based on the Updater class, which was removed starting version 20 of the python-telegram-bot library. The recommended approach now is to use the new Application class. Upgrade your package with ‘pip install python-telegram-bot --upgrade’ and update your bot code accordingly. The migration guide in the official documentation should help with the changes required. This update is required to ensure compatibility with the latest library improvements and security enhancements.
