Installing Ruby 2.5 on Mac M1

installing-ruby-2.5.1-on-m1.md

I was able to get Ruby 2.5.1 building on M1 by following two of the steps in that GH issue...

rbenv/ruby-build#1691 (comment) rbenv/ruby-build#1691 (comment)

I installed readline and openssl with standard brew install.

brew install readline
brew install openssl

Then I set this in my ~/.zshrc..

# Homebrew
export PATH=/opt/homebrew/bin:$PATH
export PATH="/opt/homebrew/sbin:$PATH"
# rbenv
export RBENV_ROOT=/opt/homebrew/opt/rbenv
export PATH=$RBENV_ROOT/bin:$PATH
eval "$(rbenv init -)"
# openssl
export PATH="/opt/homebrew/opt/[email protected]/bin:$PATH"
export LDFLAGS="-L/opt/homebrew/opt/[email protected]/lib"
export CPPFLAGS="-I/opt/homebrew/opt/[email protected]/include"
export PKG_CONFIG_PATH="/opt/homebrew/opt/[email protected]/lib/pkgconfig"
export RUBY_CONFIGURE_OPTS="--with-openssl-dir=/opt/homebrew/opt/[email protected]"

Then I ran this command:

RUBY_CFLAGS="-Wno-error=implicit-function-declaration" rbenv install 2.5

I haven't been able to test this yet, but @samik3k has reported that this no longer works, but that the following command does.

RUBY_CFLAGS=-DUSE_FFI_CLOSURE_ALLOC rbenv install 2.5.8

Please reply and let me know if this works for you and I'll update the steps above as I don't have Ruby setup on my M1 Mac right now.

@zaheeraws that worked for me for 2.5.3, thanks! The flags above still gave me an error.

worked for 2.5.8, on an m1 max mac studio

worked for 2.5.3 on my macbook air M1.
Good catch!

Thank you! Worked well on MBP 14 for Ruby 2.5.8!

Also helped me, thanks! M1, Ruby 2.5.9.

You should use brew install [email protected] since homebrew now install openssl 3 by default.

Not working anymore, rbent and rvm variant, compilation error. Anyone know how to fix it on macos 13.0.1?

Working RUBY_CFLAGS=-DUSE_FFI_CLOSURE_ALLOC rbenv install 2.5.8

Working RUBY_CFLAGS=-DUSE_FFI_CLOSURE_ALLOC rbenv install 2.5.8

It worked like a charm. Thanks a lot.

Working RUBY_CFLAGS=-DUSE_FFI_CLOSURE_ALLOC rbenv install 2.5.8

worked for m2 - thanks a lot!

This worked for me for Ruby 2.5.3. Thanks!

RUBY_CFLAGS=-DUSE_FFI_CLOSURE_ALLOC rbenv install 2.5.3

omg after spending hours on it, this worked for 2.5.1. thank you!!!

btw i used RUBY_CFLAGS=-DUSE_FFI_CLOSURE_ALLOC rbenv install 2.5.1

RUBY_CFLAGS=-DUSE_FFI_CLOSURE_ALLOC rbenv install 2.5.8

Worked for me.. thank you so much!

RUBY_CFLAGS=-DUSE_FFI_CLOSURE_ALLOC rbenv install 2.5.9

Worked for me

Working RUBY_CFLAGS=-DUSE_FFI_CLOSURE_ALLOC rbenv install 2.5.8

I am getting this error

Now getting this:

I am now sure how to go about clearing this?

thanks @Tokiyomi, this command worked for me for m1 mac.
RUBY_CFLAGS=-DUSE_FFI_CLOSURE_ALLOC rbenv install 2.5.0

Just this command worked for me:

RUBY_CFLAGS="-Wno-error=implicit-function-declaration" rbenv install 2.5.5

It's works for me

oh, thank you a lot!

RUBY_CFLAGS=-DUSE_FFI_CLOSURE_ALLOC rbenv install 2.5.9
working on MacOS 14 and M2 processor. thank you! <3

ruby-install 2.5.8 -- CFLAGS="-DUSE_FFI_CLOSURE_ALLOC" worked on MacOS 14.1 Sonoma and M3. Thank you!

Just this command worked for me:

RUBY_CFLAGS="-Wno-error=implicit-function-declaration" rbenv install 2.5.5

Thanks @zaheeraws that worked for me!

RUBY_CFLAGS=-DUSE_FFI_CLOSURE_ALLOC rbenv install 2.5.0

This worked on MacOS 14.2 M2. Thank you!

Got 2.4.9 working on a M1 with
RUBY_CFLAGS=-DUSE_FFI_CLOSURE_ALLOC rbenv install 2.4.9

Got the version 2.5.1 working on a Mac M3

RUBY_CFLAGS=-DUSE_FFI_CLOSURE_ALLOC rbenv install 2.5.1

For me, a following command worked:

RUBY_CFLAGS=-DUSE_FFI_CLOSURE_ALLOC RUBY_CONFIGURE_OPTS="--with-openssl-dir=/opt/homebrew/opt/[email protected]" asdf install ruby 2.5.1
