Ruby 2.7.4 & 3.0.0 fails on macOS Big Sur (11.2.3): undeclared identifier RSA_SSLV23_PADDING

Trying to install Ruby 2.7.4 & Ruby 3 on Intel Mac 11.2.3 and I'm seeing the following error during compilation (installing using ruby-install (https://github.com/postmodern/ruby-install). I'm seeing the following error:

                                                   ^

!!! Compiling ruby 2.7.4 failed!

Also, FYI:

❯ openssl version
LibreSSL 2.8.3

Solution

Just for future reference, if someone is facing something similar with rvm just uninstall openssl@3 using brew and instead install openssl@1.1

Edit: In recent RVM versions this has been fixed, but still needs path to openssl

rvm install ruby-<version> --with-openssl-dir=$(brew --prefix openssl@3.0)
