Building ruby 3.x.x fails on Mac M1/M2 with openSSL error

When attempting to build Ruby on a Mac M1/M2, you may encounter an openSSL error that is caused by a conflict with OpenSSH.

ruby-install ruby 3.x.x

!!! Compiling ruby 3.1.3 failed!

To resolve this issue, you can run the following command to update your environmental variables that are referenced when building Ruby.

export PATH="/opt/homebrew/opt/openssl@1.1/bin:$PATH"
export PKG_CONFIG_PATH="/opt/homebrew/opt/openssl@1.1/lib/pkgconfig"
export LDFLAGS="-L/opt/homebrew/opt/openssl@1.1/lib"
export CPPFLAGS="-I/opt/homebrew/opt/openssl@1.1/include"

NOTE: This assumes that OpenSSL@1.1 is installed via homebrew. If you don’t already have it installed, you can use the below command to install it with homebrew, alternatively you can modify the paths above to match your installed version of openSSL.

brew install openssl@1.1
