Cocoapods shows "undefined method `exists?' for File:Class" error #141167
Description
Steps to reproduce
I run flutter build macos on a project with native dependencies (Firebase) so that cocoapods needs to run. It used to work just fine, but now I'm getting the error message undefined method exists?' for File:Class. That method is called File.exists` in Ruby 3.2 … which is used by my version of cocoapods internally, so it seems. It might have started with Xcode 15.2 which I just installed, but I'm not sure.
I'm on Sonoma 14.2.1, using Homebrew 4.2.3, cocoapods 1.14.3 (which is dependent on Ruby 3.2.2 although this version isn't in the PATH) installed via brew install cocoapods, Xcode 15.2 and Flutter 3.18.0-19.0.pre.123
Expected results
It should run.
Actual results
[!] An error occurred while processing the post-install hook of the Podfile.
