Setting up a local development environment involves installing Ruby, its dependencies, and the necessary tools on your computer.

Keep in mind that local development might be limited by hardware constraints and requires manual updates and backups.

Setting up your local Ruby environment

To start developing with Ruby on your local machine, you must install Ruby and its accompanying dependencies.

We will use asdf, a versatile tool that allows you to manage multiple programming environments and effortlessly switch between versions on a per-project basis.

Although the asdf tool may initially seem unfamiliar, it can greatly simplify your Ruby development experience by saving time and preventing issues associated with managing multiple environments.

In addition to Ruby, asdf works with many other languages such as Node.js, Python, and PHP, making it a valuable tool in your development toolkit.

Installing asdf

To install asdf, follow the steps outlined in the official documentation.

After installation, verify that asdf is functioning as expected by running:

asdf version

If the installed version appears, asdf is ready for use.

Installing Ruby using asdf

To install the latest version of Ruby using asdf, execute the following commands:

asdf plugin add ruby https://github.com/asdf-vm/asdf-ruby.git
asdf install ruby latest
asdf global ruby latest

After installation, confirm that Ruby works correctly by checking its version with:

ruby --version

This should return the Ruby version, indicating that it is properly installed and ready to use.
