I'm getting error on macOS with M1 CPU

python-telegram version: 0.18.0

from telegram.client import Telegram

Telegram(
    api_id='api_id',
    api_hash='api_hash',
    phone='+31611111111',
    database_encryption_key='changekey123',
)

Traceback (most recent call last):

Issue is fixed by replacing telegram/lib/darwin/libtdjson.dylib file to Universal 2 version

Universal 2 version can be taken from https://github.com/up9cloud/ios-libtdjson Releases -> libtdjson.xcframework.tar.gz -> macos-arm64_x86_64/libtdjson.dylib

Thanks, it works! Though to prevent Mac from blocking an unknown lib one also needs to run xattr -r -d com.apple.quarantine telegram/lib/darwin/libtdjson.dylib.

Hi,

I think that provide libtdjson.{dylib,so} is just a way to facilitate the user experience , but the best way would be get tdlib via the package manager.

In any case you don't need to replace file. If it does not work for you you can specify the lib in this way:

Telegram(
    api_id='api_id',
    api_hash='api_hash',
    phone='+31611111111',
    database_encryption_key='changekey123',
    library_path='your_libtdjson_path_here'
)
