Problems to run PyCall in WSL2

[Sapiosonic]

I'm running a Ubuntu 22.04.3 LTS in WSL2 and I am facing the very same issue in two different machines. When I run a ruby script to test if PyCall is working, I've used the example provided in the README. I recieve the same error bellow

I've faced the same issue in a Ubuntu Mate 1.26.0. Is there any specific way to run a script

Hmm, it's working for me on WSL2 ubuntu. Care to share a sample script so I can see if it's something about what you're running?

@Sapiosonic Please read the error message you've encountered. "cannot load such file -- fiddle (LoadError)" means the Ruby you used couldn't load fiddle standard library. I don't know why your Ruby cannot load fiddle. Maybe some dependencies are broken, or simply your Ruby doesn't have fiddle. But, it clearly isn't due to pycall.
