rbenv and Apple m1. Failed installing ruby 3.2, 2.7 and 2.6

Question

I can't install any ruby version with rbenv. I tried 2.6.10 2.7.7 or 3.2.0.

This is the error I got when executing:

❯ rbenv install 3.2.0

When installing with Homebrew it's working. I don't know what to do. Should rbenv even suppose to work with m1 computers?

I have MacOS 13.1

Setting the environment variable below solves the problem:

export RUBY_CONFIGURE_OPTS="--with-zlib-dir=$(brew --prefix zlib) --with-openssl-dir=$(brew --prefix openssl@1.1) --with-readline-dir=$(brew --prefix readline) --with-libyaml-dir=$(brew --prefix libyaml) --with-gdbm-dir=$(brew --prefix gdbm)"

before running rbenv install for all versions.

Note: The configuration --with-openssl-dir=$(brew --prefix openssl@1.1) is needed only for versions 2.6.* and 2.7.* . You can (and should) remove it if you are trying to install ruby 3.*.* .

For 2.6 and 2.7 sometimes this environment variable also needed:

export RUBY_CFLAGS="-Wno-error=implicit-function-declaration"

If all of the above didn't work, you can install ruby with Homebrew. If you want to manage the Homebrew installed version from rbenv read this answer .
