flutter doctor - CocoaPods installed but not working

using zsh - use to work in bash
brew doctor - Your system is ready to brew.
flutter doctor gives this error

[!] Xcode - develop for iOS and macOS (Xcode 12.2)
    ✗ CocoaPods installed but not working.
        You appear to have CocoaPods installed but it is not working.
        This can happen if the version of Ruby that CocoaPods was installed with is different from the one being used to invoke it.
        This can usually be fixed by re-installing CocoaPods. For more info, see https://github.com/flutter/flutter/issues/14293.
      To re-install CocoaPods, run:
        sudo gem install cocoapods

sudo gem install cocoapods

Gives this error  
dyld: Library not loaded: /usr/local/opt/gmp4/lib/libgmp.3.5.2.dylib  
  Referenced from: /Users/puser/.rvm/rubies/ruby-2.5.1/bin/ruby  
  Reason: image not found  
zsh: abort      sudo gem install cocoapods

I can't get this error above corrected - any suggestions?

which pod

/Users/puser/.rvm/rubies/ruby-2.5.1/bin/pod

which gem

gem () {
    \typeset result
    (
        \typeset rvmrc
        rvm_rvmrc_files=("/etc/rvmrc" "$HOME/.rvmrc") 
        if [[ -n "${rvm_prefix:-}" ]] && ! [[ "$HOME/.rvmrc" -ef "${rvm_prefix}/.rvmrc" ]]
        then
            rvm_rvmrc_files+=("${rvm_prefix}/.rvmrc") 
        fi
        for rvmrc in "${rvm_rvmrc_files[@]}"
        do
            [[ -s "${rvmrc}" ]] && source "${rvmrc}" || true
        done
        unset rvm_rvmrc_files
        command gem "$@"
    ) || result=$? 
    hash -r
    return ${result:-0}
}

which ruby

I saw many people suggesting using rvm to manage rudy. I tried it but failed. In fact, flutter just wants me to install cocoapods. Why not simply install cocoapods directly? I ended up using

brew install cocoapods

solved this problem

With the latest version of Flutter (require ruby 2.7.2) so these steps below worked for me:

  1. curl -L https://get.rvm.io | bash -s stable
  2. rvm install ruby-2.7.2 
  3. rvm --default use 2.7.2 
  4. sudo gem install cocoapods

First install brew package manager for Mac. https://brew.sh

If you use macOS, system Ruby is not recommended. and you should not use it. its for system specific use. you need to install another one for user.

brew install rbenv

then install the latest version of ruby. as today its 3.1.0

rbenv install 3.1.0 --verbose

then set the global version of Ruby to be used in all shells

rbenv global 3.1.0

close the terminal and reopen it again, to affect the changes.

and finally install cocoapods

gem install cocoapods

as you see you don't use sudo command. because you are not overriding system specific configurations. when you need to use sudo command means you are doing something that you should avoid it.

if you are using fastlane and still complaining about cocoapods, even cocoapods is installed properly, reinstall fastlane again:

brew uninstall fastlane
gem install fastlane

if you have issues with the ruby zlib extension when building 3.1.0:

  1. brew install zlib
  2. LDFLAGS=-L/usr/local/opt/zlib/lib CPPFLAGS=-I/usr/local/opt/zlib/include rbenv install 3.1.0

@Aboonajmi's answer was really helpful but I would like to add something that may be more user-oriented in the case of Apple Chip M1/M2, for every command if you encounter fail result, add the "arch -arm64" for the command to run properly, for example:

arch -arm64 brew install rbenv

or

sudo arch -arm64 gem install cocoapods

Notice to use sudo when installing with gem.

Hope my information can be helpful.

Using the suggestion for this post, I was able to get cocoapods reinstalled with the commands below
gem native extension error while installing cocoapods

Open Terminal

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

Reopen Terminal

rvm install ruby-2.6

rvm use ruby-2.6.5

rvm --default use 2.6.5

Then this installed cocoapods as expected

sudo gem install cocoapods
