Install Ruby on Rails (web development) environment on Chromebook using Crouton

Web development on a Chromebook. Is it possible? Even if its possible, does it work well? It does! I develop web applications, mainly using Ruby on Rails on my Chromebook. I used to use to 15 inch MacBook Pro, but since I travel almost every month, after a while, lugging my macbook around was a real pain in the back. For the last year or so I've been using an Asus C302A Flip Chromebook. At first, I wasn't sure the Chromebook was going to be able to cope with web app development using Ruby on Rails, but I was pleasantly surprised.

In this post I'm going to document how I set up ubuntu on my Chromebook for local web development. Please note that I've already put my Chromebook in developer mode, installed Crouton and created an ubuntu chroot. If you haven't done it here's a guide on installing crouton and chroots on your chromebook.

Once you're all set up, follow these steps to set up Ruby on Rails on your new Ubuntu Chroot.

  1. Open Chrome
  2. Press CTRL + ALT + T
shell
sudo enter-chroot -n ubunutu

The '-n' let's you pass a name to your chroot. Hopefully you named your chroot. If you only have one chroot, you can skip the '-n ubuntu'. If you have multiple chroots, and you didn't name yours then the default name will be the release name, something like 'xenial'.

Congratulations, you're now logged in to your virtual ubuntu machine. Now for the fun part.

Install Git:

sudo apt-get install git

Install Curl:

sudo apt-get install curl

Install RVM (Ruby Version Manager)

sudo curl -sSL https://get.rvm.io | bash -s stable

Ah, I got a failure. Something to do with GPG keys.

sudo curl -sSL https://rvm.io/mpapis.asc | gpg --import -

OK now rerun the previous curl command to get rvm. You should see a success message like this:

Installation of RVM in /home/user/.rvm/ is almost complete:

  * To start using RVM you need to run `source /home/user/.rvm/scripts/rvm` or source ~/.rvm/scripts/rvm
    in all your open shell windows, in rare cases you need to reopen all shell windows.

Let's check we have the latest version installed.

rvm get stable

Now we need to get the system ready for Ruby

rvm requirements

What ruby versions can we install? Let's check.

rvm list rubies

2.4 is the latest. If I'm not mistaken the app I want to work on runs on 2.2, so I'm going to install that.

rvm install 2.2

Wait a while….

ruby -v
ruby 2.2.7p470 (2017-03-28 revision 58194) [x86_64-linux]

To avoid conflicts between ruby versions, we'll create a gemset to use with this ruby version.

rvm use 2.2@r2.2_default --create --default
Using /home/chirag/.rvm/gems/ruby-2.2.7 with gemset r2.2_default

Before we install rails, we should tell rubygems not to create any documentation. Use your text editor to edit the file. I'm using VIM.

vim ~/.gemrc

Add the following two lines in the file and save.

install: --no-rdoc --no-ri
update:  --no-rdoc --no-ri

Now you can install rails. I'm using 4.2.10

gem install rails --version 4.0.8

We need to perform some one time set up if this is the first time you're using git.

git config --global user.name "Your Full Name"
git config --global user.email your.email@mydomain.com
git config --global alias.co checkout

Once you're in a folder where you want to work

git init

If you're working on code that's already on a repository

git remote add origin git@bitbucket.org:username/projectname.git

To use this we need to set up ssh keys for bitbucket.

ssh-keygen -f ~/.ssh/<bitbucketusername>
ssh-add ~/.ssh/<username>
cat ~/.ssh/<username>.pub

Paste the contents into bitbucket. Follow these instructions. 

Now grab your repository. Use clone instead of pull as it will set up remote tracking.

git clone git@bitbucket.org:team/project.git

You should be ready to roll if you downloaded an existing rails project. Enjoy!
