Required ruby-2.7.2 is not installed. To install do: ‘rvm install “ruby-2.7.2″‘” MacOS

Problem

While trying to run a ruby app, I got an error

Required ruby-2.7.2 is not installed. To install do: 'rvm install "ruby-2.7.2"'" MacOS 

Tried to run the command: rvm install "ruby-2.7.2" but it always fail.

Reason

 I installed opensll@3 default into mac so that one is not supporting old ruby versions anymore

Solution

• Make sure that you have openssl@1 installed through:

brew install openssl@1

• Use openssl@1 to install ruby-2.7.2 using this command:

rvm install 2.7.2 -- --with-openssl-dir=$(brew --prefix [email protected])
