homebrew-openjdk VS asdf

The adoptopenjdk project has instructions: https://github.com/AdoptOpenJDK/homebrew-openjdk

Lmao. Use ASDF to install multiple versions of python, nodejs, ruby, etc locally. Don't mess with system-wide interpreters.

https://asdf-vm.com/ - like NVM but for all languages

There's a Deb for python, but I tend to use https://asdf-vm.com ... It is like a version manager for a bunch of tools like python, nodejs, and PHP. Let's you have a bunch of different versions installed, and switch to them at will.

Just use https://asdf-vm.com

I see you called out nvm in a negative light, but I'd like to suggest asdf. It's a general-purpose version manager that I've been very happy with for managing nearly every run-time in my environment. It can be used for deno with the deno plugin

1) Set the correct ruby version. I use asdf-vm to manage my ruby and JS version. It can also manage other languages, but these two are my main. I also typically want any changes I make to the ruby version to be local to that project only. Which asdf can do through the command asdf local language version # => asdf local ruby 2.7.4

I use asdf for these cases, and it tends to be handy for other tools too. Honestly the apt version is first prize if you don't have another requirement that rules it out.

I recently debugged a similar issue with a Macbook Pro M1 user but his issue was that node was managed by ASDF and ASDF made the Node.js invocation significantly slower: https://github.com/asdf-vm/asdf/issues/290

You probably want to use a Ruby version manager like RVM, rbenv, or asdf to get Ruby installed. Those options will make handling Gems (Ruby libraries) easier. Please make sure you follow their installation instructions carefully. Restart your shell (Terminal) when you're done.
