Unveiling the Ruby Elegance:
A Step-by-Step Guide to Installing Ruby on Ubuntu 20.04
In the vibrant world of programming languages, Ruby stands out as a gem, known for its elegant syntax and object-oriented approach. If you’ve set your sights on harnessing the power of Ruby for your projects, this guide is your beacon in the open-source sea. Ubuntu 20.04, a stalwart in the Linux realm, is our canvas for this masterpiece. In this intricate dance between code and operating system, let’s embark on a journey that transforms your Ubuntu environment into a Ruby sanctuary.
Prerequisites and the Command-Line Overture
The Prelude Unfolds:
Before we dive into the Ruby symphony, we must ensure our stage is set. First, open the terminal, the conductor’s wand in our hands. Update and upgrade the system, ensuring a harmonious rapport between Ubuntu and the forthcoming Ruby gem. The command ‘sudo apt update && sudo apt upgrade -y’ orchestrates this, bringing your system to the forefront of readiness. Next, we summon essential prerequisites with ‘sudo apt install -y curl gpg’. The stage is set; the instruments are tuned.
The Command-Line Overture:
Now, the terminal becomes our gateway to Ruby glory. It’s time to invoke the keyring with ‘gpg –recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB’. The keys, like cryptic melodies, unlock the trust between your system and the Ruby version manager. With the keys in place, the curtains rise on RVM (Ruby Version Manager). Install it seamlessly using ‘curl -sSL https://get.rvm.io | bash -s stable’. The stage is now equipped with the magic of version control.
The Ruby Ballet:
Version Selection and RVM Mastery
The Ruby Ballet Unfurls:
Ruby, a language with many facets, offers a range of versions. Choose your leading dancer by running ‘rvm list known’ and marvel at the array of Ruby releases. Select your version with ‘rvm install ruby_version’, substituting ‘ruby_version’ with your chosen gem. Witness the installation dance across your screen, a ballet of code transforming into a fully-fledged Ruby interpreter. Conclude this act with ‘rvm use ruby_version –default’, ensuring your system bows to the chosen Ruby gem in every performance.
RVM, our backstage pass to Ruby utopia, offers a plethora of commands. To bask in its full glory, acquaint yourself with ‘rvm list’, which unveils the installed Ruby versions. The graceful ‘rvm use’ command lets you switch between them effortlessly. For a show-stopping finale, update RVM using ‘rvm get stable –autolibs=enable’. This command ensures RVM stays attuned to the latest Ruby developments, a continuous evolution that mirrors the dynamic nature of the programming world.
The Bundler and Gemsets Waltz
Gem Ensemble Unveiled:
Ruby’s strength lies not only in its core but also in its expansive gem ecosystem. Enter Bundler, the choreographer of dependencies. Install it with ‘gem install bundler’. This gem orchestrates the dependencies of your Ruby projects, ensuring a seamless dance of code components. Witness the elegance of ‘gem list’ to marvel at the gems adorning your Ruby environment, each a unique contributor to the grand symphony of your programming repertoire.
The Gemsets Waltz:
Gemsets, a distinctive feature of RVM, enable the creation of isolated environments for different projects. Picture this as dancers in different costumes, each gracefully executing its routine without stepping on the toes of others. Create a gemset with ‘rvm gemset create gemset_name’, and waltz into its embrace with ‘rvm gemset use gemset_name’. Gemsets ensure your projects dance in harmony, each maintaining its individual grace without interfering with the elegance of others.
Embark on this Ruby odyssey, where the Ubuntu stage transforms into a haven for elegant code. The syntax becomes your ballet, the gems your orchestra, and RVM the conductor guiding the entire performance. As you stand amidst the beauty of your Ruby environment on Ubuntu 20.04, let the code resonate with the eloquence of a timeless masterpiece. The journey has just begun; the curtain rises on your Ruby narrative.
