IRuby
IRuby is a Ruby kernel for Jupyter project.
Try IRuby
You can try IRuby with a sample notebook on Binder (the same link as the banner placed above):
https://mybinder.org/v2/gh/RubyData/binder/master?filepath=ruby-data.ipynb
The following URL launches JupyterLab directly on Binder.

Installation
Requirements
If both ffi-rzmq and cztop are installed, ffi-rzmq is used. If you prefer cztop, set the following environment variable.
export IRUBY_SESSION_ADAPTER="cztop"
- We recommend the Pry backend for full functionality.
- If you want to install the latest version of IRuby from the source code, try specific_install.
gem specific_install https://github.com/SciRuby/iruby
Ubuntu
Install Jupyter.
Ubuntu 17+
sudo apt install libtool libffi-dev ruby ruby-dev make
sudo apt install libzmq3-dev libczmq-dev
gem install ffi-rzmq
gem install iruby --pre
iruby register --force
Ubuntu 16
CZTop requires CZMQ >= 4.0.0 and ZMQ >= 4.2.0. The official packages for Ubuntu 16.04 don't satisfy these version requrements, so you need to install from source.
sudo apt install libtool libffi-dev ruby ruby-dev make
sudo apt install git libzmq-dev autoconf pkg-config
git clone https://github.com/zeromq/czmq
cd czmq
./autogen.sh && ./configure && sudo make && sudo make install
gem install cztop
gem install iruby --pre
iruby register --force
Windows
Install git and Jupyter. DevKit is necessary for building RubyGems with native C-based extensions.
Install ZeroMQ.
pacman -S mingw64/mingw-w64-x86_64-zeromq
gem install ffi-rzmq
gem install iruby --pre
iruby register --force
macOS
Install ruby with rbenv or rvm. Install Jupyter.
Homebrew
brew install automake gmp libtool wget
brew install zeromq --HEAD
brew install czmq --HEAD
# export LIBZMQ_PATH=$(brew --prefix zeromq)/lib
# export LIBCZMQ_PATH=$(brew --prefix czmq)/lib
# gem install cztop
gem install ffi-rzmq
gem install iruby --pre
iruby register --force
MacPorts
If you are using macports, run the following commands.
port install libtool autoconf automake autogen
gem install ffi-rzmq
gem install iruby
Docker
Try RubyData Docker Stacks. Running jupyter notebook:
docker run -p 8888:8888 rubydata/datascience-notebook
Installation for JRuby
You can use Java classes in your IRuby notebook.
- JRuby version >= 9.0.4.0
- cztop gem
- iruby gem
After installation, make sure that your env
is set up to use jruby.
$ env ruby -v
If you use RVM, it is enough to switch the current version to jruby.
If you have already used IRuby with a different version, you need to generate a new kernel:
$ iruby register --force
Notebooks
Take a look at the example notebook and the collection of notebooks which includes a Dockerfile to create a containerized installation of iruby and other scientific gems. You can find the prebuild image at dockerhub.
