Hello. I am a Ruby fan.
I tried running Ruby in Google Colaboratory.
Open Google Colaboratory.
Run the following commands.
!apt-get install ruby-dev
!sudo apt install libtool libffi-dev ruby ruby-dev make
!sudo apt install libzmq3-dev libczmq-dev
!gem install ffi-rzmq rake
!gem install specific_install
!gem specific_install https://github.com/SciRuby/iruby
!iruby register
Install your favoirite gems for data science(Optional).
!gem install awesome_print
!gem specific_install https://github.com/SciRuby/daru
!gem specific_install https://github.com/SciRuby/daru-view
!gem install numo-narray
!gem install rumale
Then, Upload a Ruby ipynb into Colab using File -> Upload Notebook.
{
"nbformat": 4,
"nbformat_minor": 0,
"metadata": {
"colab": {
"name": "ruby.ipynb",
"version": "0.3.2",
"provenance": [],
"collapsed_sections": []
},
"kernelspec": {
"name": "ruby",
"display_name": "ruby 2.5.1"
}
},
"cells": [
{
"metadata": {
"id": "BpxZ_k6Qv84W",
"colab_type": "code",
"colab": {}
},
"cell_type": "code",
"source": [
"puts \"hello world\""
],
"execution_count": 0,
"outputs": []
}
]
}
Now you can run your ruby scripts!
have a fun day!
Check if the ruby kernel is registered in jupyter (Python notebook)
jupyter kernelspec list

Hi! thank for this, is there anyway to set up google CoLab to boot up with ruby, for example have it preinstalled and that way we could just open up a ruby notebook
the google CoLab website links to this git
But I am sure how to install it. I've already tried and failed :(
either way thanks for this!!
Hello. PhillipMaire
You are right. Now the method of installing IRuby needs to be changed.
If you can't start Ruby, you can use the following command to check if the kernel is installed.
Regards.
Hey so this worked great! I got the kernelspec list to list out ruby. I dont know how to initiate the ruby session though. you said to change the runtime to ruby but when I go to runtime dropdown box runtime seems to just be related to the processing unit type (GPU CPU TPU). How would I switch to ruby? also I am using a mac and I noticed when I run "!jupyter kernelspec list" I get
Available kernels:
ruby /root/.local/share/jupyter/kernels/ruby
ir /usr/local/share/jupyter/kernels/ir
python2 /usr/local/share/jupyter/kernels/python2
python3 /usr/local/share/jupyter/kernels/python3
swift /usr/local/share/jupyter/kernels/swift
as pictured. The ruby directory has a period before local, which I know for mac is indicating a hidden folder. I am wondering if there is an issue here?
thank you for your work on this!

It looks like you installed the ruby kernel correctly. In addition to the hardware accelerator, I think you'll see a comobobox to select a language.
(I tried to change the language of GoogleColab's settings to English to take the screenshot, but was unable to do so for some reason. Instead I found cat mode and corgi mode.)
Ruby's kernel isn't officially supported by Google, so the installation location is different, and that's okay I guess!
Click the save button to start a Ruby session.
Oh I see. I dont have that option “Runtime type”. I looked into it and it seems I need a notebook which has this already, I think??? This link to stack overflow gives a link to a java notebook which activate that dropdown box for me. But it only has jar and python (even after I install ruby in that notebook).
stackoverflow.com/questions/623036...
here is an example of it working with that java notebook from the link
dev-to-uploads.s3.amazonaws.com/i/...
here is what mine looks like when I open a new notebook and install ruby
dev-to-uploads.s3.amazonaws.com/i/...
I think this has something to do with your tutorial where you upload the ruby notebook??? I saved it and uploaded it but I must not be doing it right because it just looks like this and doesnt affect anything
dev-to-uploads.s3.amazonaws.com/i/...
dev-to-uploads.s3.amazonaws.com/i/...
dev-to-uploads.s3.amazonaws.com/i/...
I see. That's odd....
You will need to upload a new notebook.
My article is out of date, so please use the latest version of the Notebook made by Goto, who wrote an article on how to use Ruby on Google colab yesterday. It might work fine.

(Don't worry about the Japanese comments in the notes.)
You may also find the article made by Goto helpful. (This is a Japanese article from a Dev.to-like site called Qiita, which you can read using Google Translate.)

yesssssssssss!!!!! that worked! thank you so much for your guidance!!! I made a google colab file with english comments and sections for other people to use if they want to. credited the original author and also you since you helped me make it work! thanks again!!!!

Hi, unfortunately I have a problem.
I have done all the steps. but when I run, the command puts "Hello World!" tells me:
File "", line 1
puts "hello world"
^
SyntaxError: invalid syntax
and then
Unrecognized runtime "ruby"; defaulting to "python3"
Anyone know why?
I just tried this and on the last step got this error:
OSError: [Errno 2] No such file or directory: 'ruby'
Did Google shut this down?
Hi David Rea
This trick still works. I updated the text.
If this does not solve the problem,
jupyter kernelspec list. If the Ruby kernel is registered, just restart the runtime.Thank you for your report.
Got it working, thanks!
