Create a Discord Bot on Your Raspberry Pi With Python and Discord.py
This article will get you up and running with a Discord bot on your Raspberry Pi using the Discord.Py library.
The code has been updated to reflect Discord.Py’s re-write.
You can always view latest code, and more examples for this post, here: https://github.com/gngrninja/blog/tree/master/DiscordBotPi
This assumes that you've installed and are using Raspbian.

If you’ve installed Python 3.7, you’ll need the development version of Discord.py. Check out the instructions for installing that over at their developer’s README. It is strongly recommended to stay on 3.6.x, however.
Create app and invite bot to your server
2. Click "New App"
3. Give it a name, and then click "Create App"
4. Click "Create a Bot User"
5. Keep note of the Token, as you'll need that later.
6. Invite the bot to your server
a. Use the following URL to invite the bot to your server:
(Replace your_client_id_goes_here with your bot's client ID)
7. You should now see the bot in your server (offline)
First you'll want to ensure your Raspbian installation is up to date. To do this, run the following commands:
1. Update package lists
sudo apt-get update
2. Upgrade packages
sudo apt-get upgrade
3. Clean things up
sudo apt-get dist-upgrade
4. Reboot your Pi!
Install Pre-Requisites for Python 3.6.x and Discord.Py
The latest version of Raspbian (9.x/Stretch) ships with Python 3.5.3 (which should work great with discord.py).
If you'd like to upgrade your OS to Stretch, follow this article.
To check which version you have, run:
If you are running Stretch, great! Click here to skip to the next step. Otherwise, continue below.
1. Install libssl-dev (to ensure we can use pip when we install the newest version of Python)
sudo apt-get install libssl-dev
2. Install libffi-dev (to ensure audio works with the Discord bot)
sudo apt-get install libffi-dev
3. Install libsqlite3-dev (this will be handy, as it installs libraries needed to install sqlite3 support)
sudo apt-get install libsqlite3-dev
Install Python 3.6.x
1. Grab the latest version of Python 3.x from https://www.python.org/downloads/
2. Extract the files, and enter the directory
tar xzvf Python-3.6.0.tgz
3. Run configure to check for dependencies, and get ready to build the Python installation
(This will take 2-5 minutes)
4. Run make to start compiling the software
(This will take 15-30 minutes)
5. Install Python 3.6.x
(This will take 10-15 minutes)
sudo make install
6. Reboot your Pi!
Install Discory.Py, and get a bot working
1. Install latest version of the Discord library for Python (Discord.Py)
sudo python3 -m pip install -U discord.py[voice]
2. Create a bot to test it out
a. Create directory
b. Move to that directory
c. Create an empty file
d. Edit the file
e. Copy/Paste the following content in the editor (be sure to change your_token_here to your bot's token):
import discord from discord.ext import commands TOKEN = '' description = '''ninjaBot in Python''' bot = commands.Bot(command_prefix='?', description=description) @bot.event async def on_ready(): print('Logged in as') print(bot.user.name) print(bot.user.id) print('------') @bot.command() async def hello(ctx): """Says world""" await ctx.send("world") @bot.command() async def add(ctx, left : int, right : int): """Adds two numbers together.""" await ctx.send(left + right) bot.run(TOKEN)
f. Save the file using CTRL+X, and "y"
g. Run your bot!
Test Out Your Bot
1. Go to the Discord server where you've invited your bot to , and try issuing the ?help command
2. Once you verified that works, try the other ones as well!
