You can try this command

sudo gem uninstall -aIx
rm -rf ~/.gem
sudo gem install cocoapods

sudo chown -R $USER ~/Library/Caches/CocoaPods

For me, install a new version of ruby resolved this issue.

curl -L https://get.rvm.io | bash -s stable
source ~/.rvm/scripts/rvm
rvm list known
rvm install 2.7.2
sudo gem install cocoapods

Same issue. Just updating gem package manager is works for me

gem update

Terminal will display installing 'ffi'

Successfully installed ffi-1.15.5

i solved the issue by installing the command line tool for XCode.

Just download the specific CLT from apple website

I just did a

bundle install

and that allowed me to do a pod install after upgrading (without asking me to Xcode 14).
