A local Ruby environment gives you full control, but requires a few extra steps. You install Ruby, dependencies, and tools yourself.

Installing Ruby with asdf

asdf is a flexible version manager for multiple languages including Ruby, Node.js, Python, and PHP. It makes it easy to keep projects on different versions and prevents conflicts between tools.

To get started, install asdf by following the official installation guide.

Once installed, you can verify asdf is working by running:

asdf version

If you see a version number, asdf is set up correctly.

To install the latest Ruby version:

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

Check Ruby is working:

ruby --version

This confirms Ruby is ready for use.
