need install packages and dependencies

brew install make
brew install ruby-build
brew install ruby-completion
brew install ruby
brew install autogen
brew install libffi
brew install rvm

after install check environment path.

export LDFLAGS="-L/usr/local/opt/ruby/lib"
export CPPFLAGS="-I/usr/local/opt/ruby/include"
export PKG_CONFIG_PATH="/usr/local/opt/ruby/lib/pkgconfig"
export LDFLAGS="-L/usr/local/opt/libffi/lib"
export CPPFLAGS="-I/usr/local/opt/libffi/include"
export PKG_CONFIG_PATH="/usr/local/opt/libffi/lib/pkgconfig"

now retrieve your env shell

source ~/.zshrc

Still having this problem, but I have managed to workaround this by installing another ruby version using Homebrew.

But if anyone managed to solve it without installing homebrew ruby, let us know.
