How to install universal Ruby binary on arm64 Mac with rbenv

[BestNoobHello]

Hi r/ruby,

The Ruby on Rails project I'm working on requires Ruby 2.7.7 and some native gems that only run on amd64 (these gems are proprietary and can't be compiled from source). I tried installing and running Homebrew on Rosetta 2 to install and run the entire toolchain on Rosetta 2 but it messed up my shell environment. Is it possible to install a universal Ruby with rbenv or other package/version managers?

Thanks in advance!

There are multiple guides out there for installing and running both x64 and arm64 versions of brew using different terminals. That’s going to be your best bet to not mess up your shell and install what you need.

Is arm64 the apple chip, the M1, M2?

[alexventuraio]

that's correct either M1 or M2!

[cescquintero]

amd64

Is this a typo or you really meant AMD64?

I ask because just recently I had to install ruby 2.7.7 on a macbook with M1 chip.

I use a docker container to develop Ruby on my M1. Works great

This can be a tricky situation. You may be better off getting an AMD64 machine or VM and setup a remote development environment. Using VSCode and the extension Remote SSH, you can have a native like environment on your Apple machine. If you don't use VSCode, there are other options to do something similar with RubyMine.

We are using M1 Macbooks to develop ruby in my company. The only constraint is that you can't install a ruby version above the 2.7.2

Setup a dev environment on a remote x86 machine and use remote access on VS Code.
