  • Ruby 2.1+
  • An installed build system for native extensions (on Windows, try the DevKit; installation instructions here)

Voice dependencies

This section only applies to you if you want to use voice functionality.

  • libsodium
  • A compiled libopus distribution for your system, anywhere the script can find it (on Windows, make sure it's named opus.dll)
  • FFmpeg installed and in your PATH



On Linux, it should be as simple as running:

gem install discordrb


On Windows, to install discordrb, run this in a shell:

gem install discordrb

Run the ping example to verify that the installation works (make sure to replace the username and password in there with your own or your bots'!):

ruby ping.rb


If you get an error like this when installing the gem:

ERROR:  Error installing discordrb:
        The 'websocket-driver' native gem requires installed build tools.

You're missing the development kit required to build native extensions. Download the development kit here (scroll down to "Development Kit", then choose the one for Ruby 2.0 and your system architecture) and extract it somewhere. Open a command prompt in that folder and run:

ruby dk.rb init
ruby dk.rb install

Then reinstall discordrb:

gem uninstall discordrb
gem install discordrb

If you're having trouble getting voice playback to work:

Look here:


You can make a simple bot like this:

require 'discordrb'

bot = token: '<token here>', application_id: 168123456789123456

bot.message(with_text: 'Ping!') do |event|
  event.respond 'Pong!'

This bot responds to every "Ping!" with a "Pong!".

This section is for developing discordrb itself! If you just want to make a bot, see the Installation section.

After checking out the repo, run bin/setup to install dependencies. You can then run tests via bundle exec rspec spec. Make sure to run rubocop also: bundle exec rubocop. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to
