install ruby-3.2.0 on macos

Background

• I prefer rvm over rbenv, maybe I should use rbenv insead ):
  • rvm/rvm: Ruby enVironment Manager (RVM)
  • rbenv/rbenv: Manage your app’s Ruby environment
• rvm list known not showing the latest ruby version
• rvm instal 3.2 fails
• rvm fix-permissions not working for “_rvm_log_dotted:23: permission denied” error
• I noticed these two pieces of information
  • “NOTE: Even though this is all known rubies, RVM can install many more rubies not listed :)”
  • “Because https://cache.ruby-lang.org/pub/ruby/3.2/ has no "Ruby-Preview.tar.gz" file in the directory"
  • which means it should be able to install any ruby version listed in pub/ruby/ with rvm

Steps

rvm reinstall "ruby-3.2.0" --with-openssl-dir=`brew --prefix openssl@3` # not ok, [ruby don't support openssl 3 yet.](https://github.com/ruby/openssl/issues/369)

brew uninstall openssl@3
brew reinstall openssl@1.1

# new shell
rvm reinstall "ruby-3.2.0" --with-openssl-dir=`brew --prefix openssl@1.1` --disable-binary # ok
