Do I need to reinstall my OS due to Ruby?

After trying to upgrade my flutter apps dependencies failed, I've seen a command in the call stack and tried to run it. Now I think I screwed up my local ruby installation with my workarounds. I would like to know if I could retrace my steps to get the original ruby setup without my workarounds, without reinstalling the OS or is it fine the way it is? Possible important information: - Ventura: 13.0 - XCode: 14.01 Here is a summary of what I've done: It was: sudo gem pristine ffi --version 1.15.5, but instead of fixing stuff it broken even more. Some things were missing and I tried to get back to it's original state. I've found [this](https://stackoverflow.com/a/5227550/6629386) answer. Now I tried to reinstall cocoapods which was apperantly broken by running: sudo gem install cocoapods. Didn't work out because of some missing ruby/config.h headers apperantly. After researching I once again found an [answer](https://stackoverflow.com/a/65481787/6629386) : - 1. I ran: cd /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX12.3.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/include/ruby-2.6.0/ruby - 2. There I created the systemlink: sudo ln -sf ../../../../Headers/ruby/config.h - 3. Afterwards I navigated one folder up: cd /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX12.3.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/include/ruby-2.6.0 - 4. And here I needed to do something *different* from the original answer: I needed to run: sudo ln -sf universal-darwin21 universal-darwin22 I've also installed the xcode cli 14.2 beta thing, but that didn't help either. Now the App I tried to upgrade is broken, but a different one seems to work, so I think not everything is broken on the system, at least I hope so.
