Answer 1

Seems after upgrading MacOS to v13, gem will use universal-darwin22 to compile files. If you check /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/include/ruby-2.6.0/ there is only universal-darwin21 available.
So, the solution is simple, try to create a link for universal-darwin22 then install ffi.
On terminal:
cd /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/include/ruby-2.6.0/
sudo ln -sf universal-darwin21 universal-darwin22
sudo gem install ffi
More info: "ffi issue when running pod repo update or pod install on macOS Ventura #11627" - https://github.com/CocoaPods/CocoaPods/issues/11627#issuecomment-1294998876
P. S. You need to allow Terminal to modify apps in Settings.

Answer 2

Depending on some aspects this might work for you, if you don't mind using the "SUDO" command:
sudo gem install -n /usr/local/bin cocoapods -v 1.8.4
Latest CocoaPods 1.10.0 won't work.

Answer 3

You can try:
brew install cocoapods
brew link cocoapods
