For a recommended nodeJS installation, check NVM.

Note: If this is your first time on git, it’s advisable to configure your credentials first:

git config --global user.name "Neil Calabroso"
git config --global user.email "nmcalabroso@up.edu.ph"

Also, make sure your git’s core.autocrlf setting is set to false to avoid any problems when installing rbenv.

git config --global core.autocrlf false

Install Rbenv. Complete the installation instructions including the optional part:ruby-build.

Upon installing Rbenv, restart your terminal and install Ruby 2.2.0:

rbenv install 2.2.0
rbenv global 2.2.0

gem install bundler #restart terminal after the installation

Tutorials

  • If you do not have any experience on ruby, we suggest to complete the challenge by TryRuby.
  • With the set-up above, you are now ready for your first web app tutorial. You can now start at section 3.2.
  • Since the Getting Started Tutorial is too high-level (with the use of scaffolding), it is very much suggested to read and finish the book Ruby on Rails Tutorial. This book gives a thorough explanation about the workflow of Rails, Unit-testing, Git, and Deployment.
