FrozenError in colored2 gem while running pod install in CocoaPods 1.16.2

[jerrypaulsam]

I'm encountering a FrozenError when trying to run pod install with CocoaPods 1.16.2. The error occurs during the execution of the colored2 gem, specifically in the ascii_decorator.rb file. The error message is as follows:

Steps to reproduce:

I am using Ruby 3.2.0 and CocoaPods 1.16.2. I run the command pod install on my project. The error happens during the installation process.

What I've tried:

I tried uninstalling and reinstalling the colored2 gem. I attempted updating CocoaPods to the latest version, but the issue persists. I tried clearing the CocoaPods cache (pod cache clean --all), but that didn’t help.

System Information:

Ruby version: 3.2.0 (installed via RVM)

CocoaPods version: 1.16.2

colored2 gem version: 3.1.2

macOS version: 14.6.1 (23G93)

Can anyone help me understand why this error occurs, and how I can resolve it?

Thank you!

Thanks! It looks like ascii_decorator should check if the object it's coloring is frozen and if it is, duplicate it and unfreeze.
