Installation

One of the following ways can used to install Ruby and RoR

Note - If you are unable to install Ruby due to some reason, you can still participate in bootcamp with the help of GitHub codespaces.

Once you have setup a development environment using one of the above methods, you should have rvm, node and yarn installed. You can verify your installation with the following commands.

rvm --version
node --version # >= v16
yarn --version  # >= 1.22.19

RVM

RVM allows you to easily install, manage and work with multiple ruby environments.

  • Install Ruby (3.0.5)
rvm install ruby-3.0.5
rvm --default use 3.0.5
  • Create and use a gemset week<n> where n is the session number.
rvm gemset create week_2
rvm use 3.0.5@week_2

A gemset is an isolated ruby setup. For example, you can isolate two projects using Rails 5 and Rails 6 from each other using a gemset. NOTE: Always switch to the appropriate gemset when working on a project. You can use a project rvmrc to automate this process.

  • Install Bundler (2.2.33) and Rails (7.0.4)
gem install bundler --version 2.2.33
gem install rails --version 7.0.4
