rubygems VS rbenv

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.

rbenv is a version management tool for Ruby. It allows you to switch between multiple Ruby versions without needing to mess with your system’s default Ruby installation. With rbenv, you can:

The first step was upgrading the Ruby version. I used rbenv for managing the Ruby version on my Mac. I used .ruby-version file for managing active Ruby versions.

git clone https://github.com/rbenv/rbenv.git ~/.rbenv ~/.rbenv/bin/rbenv init

If you're on your own workstation you may want to consider using rbenv to allow you to quickly switch between versions of Ruby that your other project may depend upon.

When I was technical blogging on how to learn from open-source code [1], I used it quite frequently to get unstuck and/or to figure out how to tease apart a large question into multiple smaller functions. For example, I had no idea how to break up this long `sed` command [2] into its constituent parts, so I plugged it into ChatGPT and asked it to break down the code for me. I then Googled the different parts to confirm that ChatGPT wasn't leading me astray.

If I had asked StackOverflow the same question, it would have been quickly closed as being not broadly applicable enough (since this `sed` command is quite specific to its use case). After ChatGPT broke the code apart for me, I was able to ask StackOverflow a series of more discrete, more broadly-applicable questions and get a human answer.

TL;DR- I quite like ChatGPT as a search engine when "you don't know what you don't know", and getting unblocked means being pointed in the right direction.

Let’s get started. I prefer to manage my Ruby installations on my development machine with chruby paired with ruby-install. Another outstanding set of tools is rbenv with ruby-build. I highly recommend installing Ruby with one of those two sets of tools. Follow the instructions on their project’s READMEs. For this article, I’ll be running Ruby (MRI) v3.3.0.

By setting up your environment in isolation, you can prevent yourself from a lot of issues when experimenting with code. It makes your code behave more predictable due to the defined state of the runtime environment you are working with. This article should provide you with enough information to get started, but obviously, there is a lot more power embedded in NVM, Virtual Environment and RBEnv. So make sure to check their documentation.

There is this good resource that also talk about different ruby version manager from the Rbenv repository. With some links to benchmarks of ASDF and Rbenv.
