Step-by-step guide to setting up Ruby with Rbenv on Pop!_OS 22.04
Rbenv
rbenv is a lightweight Ruby version management tool. It allows you to easily install, manage, and switch between different versions of Ruby on your system.
This is particularly useful for developers who may need to work on projects that require different Ruby versions or need to keep their development environment in sync with specific Ruby versions.
With rbenv, you can set a Ruby version on a per-project basis, ensuring that each project uses the appropriate version of Ruby.
This helps in avoiding conflicts between projects that might require different Ruby versions and ensures consistency across your development environment.
