Development Environment

We’ll be using Ubuntu Linux during this course. You have two options:

Easy Option: Use the Cloud9 development environment. You only need a computer (Windows, MacOS, or Linux) with an Internet connexion and a modern browser (Chrome, Firefox, Safari, etc.). This option does not work with tablets or smart phones, but it does work with Chromebooks.
Not So Easy Option: Install Ubuntu on a hard disc partition on your computer or on a virtual machine.
- It’s advisable to use the 64 bit 14.04.3 LTS ISO image.
- How to install Ubuntu 14.04.3 LTS.
- If you can’t or don’t want to do any changes to your computer, it’s possible to install Ubuntu in a 8 GB or larger USB flash drive or external hard drive: Installing Ubuntu to USB Drives.
- Official Ubuntu website: http://www.ubuntu.com.

NOTE: The Cloud9 development environment has Ruby 2.2 already installed.

The following instructions allow you to install Ruby 2.2 (and some additional gems used in class) on Ubuntu 14.04. On the terminal type:

sudo add-apt-repository ppa:brightbox/ruby-ng

sudo apt-get update

sudo apt-get install ruby2.2 ruby2.2-dev libsqlite3-dev

sudo gem2.2 install minitest sqlite3 sinatra

You can now run the ruby command to execute scripts, or the irb command to get an interactive Ruby shell.

NOTE: The Cloud9 development environment does not have the Ruby API command line reference installed by default.

Type on the terminal:

sudo gem install rdoc-data

sudo rdoc-data --install

You can now use the ri command to consult the Ruby API documentation.
