discord.py - 命令引发异常:OpusNotLoaded

问题描述

我正在制作一个音乐机器人，但我遇到了这个问题，我正在运行 python 3.6.8 并且它托管在 heroku 上

I was making an music bot but I had it having this problem, im running python 3.6.8 and its hosted on heroku

我听说我需要使用 discord.opus.LoadOpus 或类似的东西，但我不知道如何将它添加到我的代码以及在哪里，请帮助

I've heard I need to use discord.opus.LoadOpus or something like that but I dont know how to add it to my code and where, please help

这是我的代码

import discord
import asyncio
from discord.ext import commands

client = commands.Bot(command_prefix='!')
songs = asyncio.Queue()
play_next_song = asyncio.Event()


@client.event
async def on_ready():
    print('client ready')


async def audio_player_task():
    while True:
        play_next_song.clear()
        current = await songs.get()
        current.start()
        await play_next_song.wait()


def toggle_next():
    client.loop.call_soon_threadsafe(play_next_song.set)


@client.command(pass_context=True)
async def play(ctx, url):
    if not client.is_voice_connected(ctx.message.server):
        voice = await client.join_voice_channel(ctx.message.author.voice_channel)
    else:
        voice = client.voice_client_in(ctx.message.server)

    player = await voice.create_ytdl_player(url, after=toggle_next)
    await songs.put(player)

client.loop.create_task(audio_player_task())

client.run('TOKEN')

我有这个错误:

Ignoring exception in command play
Traceback (most recent call last):
File "/app/.heroku/python/lib/python3.6/site-packages/discord/ext/commands/core.py", line 50, in wrapped
ret = yield from coro(*args, **kwargs)

voice = await client.join_voice_channel(ctx.message.author.voice_channel)

File "/app/.heroku/python/lib/python3.6/site-packages/discord/opus.py", line 197, in __init__
raise OpusNotLoaded()
discord.opus.OpusNotLoaded

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

Traceback (most recent call last):
File "/app/.heroku/python/lib/python3.6/site-packages/discord/ext/commands/bot.py", line 846, in process_commands

推荐答案

你不需要在你的代码中添加任何东西，试着把它添加到你在 Heroku 上的 buildpacks 中:

You don't need to add anything to your code, try adding this to your buildpacks on Heroku:
