Gem 'ffi' is not installed

Answer 2

I. Open Terminal

II. curl -L https://get.rvm.io | bash -s stable

III. Close the terminal

IV. Reopen Terminal

V. rvm install ruby-3.1.1

VI. rvm use ruby-3.1.1

VII. rvm --default use 3.1.1

VIII. Then this installed cocoapods as expected by using sudo gem install cocoapods
