Installation issues with Arm Mac (M1 Chip)

[jasonsilberman]

Hey there!

I am trying to install Ruby 2.7.2 on my new Apple Silicon Mac but am running into some issues, which I think might be related to ruby-build, but not I am not 100%.

I have setup an alias on my ~/.zshrc for Homebrew like this:

alias ibrew="arch -x86_64 /usr/local/bin/brew"

I have run the following commands in order to install rbenv:

ibrew install rbenv

rbenv init

I have updated my .zshrc file with:

eval "$(rbenv init -)"
export RUBY_CONFIGURE_OPTS="--with-openssl-dir=$(brew --prefix openssl@1.1)"

And then I ran the following command:

rbenv install 2.7.2

I have also tried prefixing the rbenv command with arch -x86_64 but that did not work either.

These are the console logs that I am getting when I am trying to install Ruby:

I have the same problem, here is full log output to help you. Also on my new MacBook Pro with M1.

I tried different flags and absolutely no flags, aka rbenv install 2.7.2.

Thanks for excellent work, and Merry Christmas.

I only confirm to work native arm arch with M1 chip. I'm not sure what happened with the mix environment provided by Rosetta2.

I'm also running into the same issue with the M1 Chip MacBook Pro and am seeing the same undeclared identifier 'username_completion_function' error as described by @TheMlok.

@hsbt I installed via brew install rbenv command. How are you working with the native arch with M1 chip?

Yes.

Same issue here with my new MBA M1. Tried with Homebrew and Basic GitHub Checkout.

It seems you all mix readline compiled for ARM with Ruby for x64. That will never work properly. It's not good idea to mix these platforms together. Just use separated Homebrew for ARM and for x64.

@hsbt I believe the issue is in readline. ruby-build tries to use homebrew version while building.

Hi! Im also trying to install Ruby.

Ive been reading your post and the following answers.
I'm a bit behind on the installation, on Homebrew, as I dont know how to create a .zshrc file in my home directory export PATH="/opt/homebrew/bin:$PATH"
As seen on: https://github.com/mikelxc/Workarounds-for-ARM-mac
(Ive followed this steps before posting here)

Could you please advise on how to do this?
Not sure yet on how to do it, as Im fairly new to Mac.

Thanks!

Hello, please have you any rollout how to setup everything properly to the working state? I need to switch my ntb at job for a new one. I just followed guidelines. I installed homebrew with rosetta2 and then brew install rbenv.

Just open terminal and vim .zshrc edit the file and save :wq.

Hello, please how did you install natively? Using Homebrew or compilation, please can you give some details? I will try it. Thanks.

I have solved it. I deleted Homebrew and install it natively for ARM, installed rbenv and symlinked into /usr/local/bin. And it is working now, thanks (just a few issues in older versions, nothing dramatic.

[albertski]

@TheMlok How did you install Homebrew natively for ARM? When I tried, I get "Homebrew is not (yet) supported on ARM processors".

I installed Homebrew as shown here and got the errors shown above.

[tcannonfodder]

I had some success by using the latest Homebrew install script (which adds partial support for M1), then:

1. Installing readline from source to verify that it works (brew install -s readline)
2. installing libyaml
3. Installing Ruby 3.0.0 (to try to reduce as many potential issues as possible)

Update: 2020-12-29: I got 2.7.2 working by:

1. Manually installing the Xcode command line tools from apple's developer site
2. rbenv install 2.7.2
3. gem update to update all the installed gems (fixing native extension bugs, for example with Digest`)
4. brew install libxml2 for nokogiri support
5. gem install nokogiri -- --use-system-libraries

[albertski]

With the latest version of Homebrew I was able to install rbenv without any issues. (Also had to install openssl)
