Как заставить дискорд бота запустить песню?

Question

[Иван Стыслов]

Использую мак ос на м1, бота делал через библиотеку disnake, встрял с так называемым opus, вроде бы все скачал, но он стабильно выдает мне такую ошибку (это с использованием disnake.opus.load_opus('opus')):

The above exception was the direct cause of the following exception:

Это другая ошибка, без попытки загрузить opus:

Кусок кода с командой для запуска музыки:

Пока вместо поиска музыки стоит заглушка.
Еще интереснее, добавил
import libopus
И получил:

Exception: Could not find Opus library. Make sure it is installed.

Хотя библиотека установлена (через brew Install opus)
Нашел пару ответов, что он ищет не там эту либу, что в целом не круто, может есть варианты получше, для того, чтобы заставить бота запускать песни?

Answer 1

[Иван Стыслов]

Рассказываю, что я сделал, чтобы данный код заработал
1) скачиваем opus на ваш мак:
brew install opus
2) нужно найти, куда скачался данный файл:
brew info opus
у меня это было /opt/homebrew/Cellar/opus
3) находим исполняемый файл:
/opt/homebrew/Cellar/opus/1.3.1/lib
у меня их два libopus.dylib и libopus.0.dylib
4) далее, как вы могли заметить, он ищет libopus по трем путям:

disnake.ext.commands.errors.CommandInvokeError: Command raised an exception: OSError: dlopen(opus, 0x0006): tried: 'opus' (no such file), 
'/usr/local/lib/opus' (no such file), 
'/usr/lib/opus' (no such file), 
'/Users/similization/Programming/python/discord_bot/opus' (no such file)

, я добавил его к себе в папку проекта
5) наконец добавляем куда-нибудь в начало проекта
disnake.opus.load_opus('libopus.dylib')
и бот подключился и запустил музыку

Answer 2

[Vindicar]

Ну тебе бот пишет прямым текстом где он ищет библиотеку:

OSError: dlopen(opus, 0x0006): tried: 'opus' (no such file), '/usr/local/lib/opus' (no such file), '/usr/lib/opus' (no such file), '/Users/similization/Programming/python/discord_bot/opus' (no such file)

Найди, куда именно установился опус, и создай символическую ссылку на библиотеку по одному из указанных путей. Лучше всего по последнему, я полагаю.

Я уже понял, что он ищет ее не там, где нужно, вопрос скорее заключался в другом. Мне скорее не нравится создание подобного вида костылей, потому что либа видимо не писалась под м1 и ищет по совершенно другим путям, а что-нибудь получше этой библиотеки есть?
