Discord.py: error when the bot joins & how to make the bot play mp3 files ?

[rektile]

so i want make a discord bot that joins my channels and plays a mp3 file from my computer.
the problem is when the bot joins it gives me this error : RuntimeError: PyNaCl library needed in order to use voice.
but i know for sure pynacl is installed.
and how do i let the bot play mp3 files ?
this is the code :

import discord
from discord.ext import commands
from discord.ext.commands import Bot
import asyncio

client = discord.Client()
bot = commands.Bot(command_prefix= "#")

@bot.command(pass_context=True)
async def brent(ctx):
voice_channel = ctx.message.author.voice.voice_channel
await bot.join_voice_channel(voice_channel)

you need to install discord.py voice

run this in your terminal:
python3 -m pip install -U discord.py[voice]

i did it but still the same error :
Ignoring exception in command brent
Traceback (most recent call last):
File "C:\Usersangelo\PycharmProjectsangelo\venv\lib\site-packages\discord\ext\commands\core.py", line 50, in wrapped

await bot.join_voice_channel(voice_channel)

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

Well I dont think you have, ive just tried this and it works for me...

import discord
from discord.ext import commands

bot = commands.Bot(command_prefix= "#")

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

@bot.command(pass_context=True)
async def brent(ctx):
    voice_channel = ctx.message.author.voice.voice_channel
    await bot.join_voice_channel(voice_channel)

bot.run('token')

the bot joins the channel im in but it gives me that error so i probably cant play sound i think.
im new in python so im sorry if i say stupid things.
btw do you know how i let the bot play mp3 files or play sound from an url ?

[ewanxdd]

i suggest you learn python first before creating a discord bot, I am not going to spoonfeed code.

[rektile]

i know the basics but im new to making discord bots. the only thing i want to do is troll my friends by playing i file have

[AndyTempel]

I'm giving you a small snippet of code for playing mp3 from a file...
The code is written with discord.py rewrite and here are the docs, you should really take a look at them, because everything is explained there.

voice = await message.author.voice.channel.connect()
voice.play(discord.FFmpegPCMAudio('./res/rick_roll.mp3'))

and if you want specific length:

voice = await message.author.voice.channel.connect()
voice.play(discord.FFmpegPCMAudio('./res/rick_roll.mp3'))
counter = 0
duration = 10   # In seconds
while not counter >= duration:
    await asyncio.sleep(1)
    counter = counter + 1
await voice.disconnect()

[rektile]

thanks for helping me but i still get this error : RuntimeError: PyNaCl library needed in order to use voice

[dsluo]

Because you don't have PyNaCl installed, which is listed in the documentation as a requirement for voice.

[rektile]

thats weird maybe i installed i wrong or something. how should i install it ?

[ewanxdd]

Like I said above:
python3 -m pip install -U discord.py[voice] put that into your terminal

[rektile]

this is what i get:

and it still doesnt work

[EvieePy]

Open Command Prompt as an Administrator.

Run:
py -3.6 -m pip install -U pynacl

When running your bot:
py -3.6 my_bot_file.py

If you are using an IDE, ensure that the interpreter is the correct one.

mysterialPy thanks man , the bot joins and plays my file :D
but now it ignores my other commands :/

[rektile]

discord.ext.commands.errors.CheckFailure: The check functions for command (my other commands) failed.

[rektile]

nvm it worked thanks :)

[averwhy]

voice = await message.author.voice.channel.connect() NameError: name 'message' is not defined
Any fix?

@avrwhy Please stop necroing issues.
As the README recommends, you should join either the official discord.py server or the Discord API server for help using the library.
