Install RVM on macOS

Reference: https://nrogap.medium.com/install-rvm-in-macos-step-by-step-d3b3c236953b

First, we need to install homebrew

Install GnuPG


brew install gnupg

‣

Because of security issue, rvm uses gpg for signing. So we need to install gnupg from homebrew

Install GPG Keys

‣

So we have to use gpg before installing rvm. We have to follow up installations from document.

Install specific ruby version through rvm


rvm install 3.2.0 // or another specific version

If you use macOS, you probably can get this issue while installing ruby version. __rvm_make -j10 error. So for fixing this issue, I found good solution from github issue.

‣

I could install 3.2.0 version of ruby by following this comment.

openssl issue

The main reason we got this issue is Openssl. Homebrew uses openssl@3 default (I guess) So just simply remove openssl version 3 from homebrew, and install specific ruby version like 2.7.5. And reinstall openssl 3 again.
