M1 MAC smells good

Prerequisites: Install macports by referring to Installing MACPort on Mac Arm

1. Install Rbenv and Ruby-build

sudo port install rbenv ruby-build
Copy the code

2. Configuring environment Variables

echo 'if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi' >> ~/.profile
source ~/.profile
Copy the code

3. Lists the available Rubies

You may encounter the following error and need to specify openSSL
