why do i get Error installing cocoapods every time?

Question

Trying to work download flutter on mac ,and when i run flutter doctor i get error at xcode that says CocoaPods not installed

so i tried downloading it with "sudo gem install cocoapods"
and i get this error

Error installing cocoapods:
    There are no versions of cocoapods-downloader (>= 2.0) compatible with your Ruby & RubyGems. Maybe try installing an older version of the gem you're looking for?
    cocoapods-downloader requires Ruby version >= 2.7.4. The current ruby version is 2.6.10.210.

What can I do?
