Due to Homebew of Rosetta version, I struggled with installing ruby 3.2.2 by rbenv.
Here is the error.
*** Following extensions are not compiled:
psych:
Could not be configured. It will not be installed.
Check ext/psych/mkmf.log for more details.
*** Fix the problems, then remove these directories and try again if you want.

To eliminate this warning, please install libyaml and reinstall your ruby.
uh-oh! RDoc had a problem:
cannot load such file -- psych
run with --debug for full backtrace
make: *** [rdoc] Error 1
I tried these and it worked for me:
Uninstall Rosetta version of Homebrew
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall.sh)"
Reinstall Homebrew
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
Install libyaml
brew install libyaml
Specify libyaml's path by RUBY_CONFIGURE_OPTS arg on Ruby installation
RUBY_CONFIGURE_OPTS=--with-libyaml-dir="$(brew --prefix libyaml)" rbenv --debug install 3.2.2
