I suspect we should use os.path.join rather than string concatenation

@zbeucler2018 would you be able to investigate?

[Misteridk2022]

hmm if that's the issue What can I do to change it or another method to install it?

[pseudo-rnd-thoughts]

Without you / us fixing it or you changing a linux based system then I don't think there is anything you can do.

Also having the same issue, is there a quick fix for the slash going the wrong way?

I'm happy to investigate this and I think using os.path.join is a much better solution. However, I am not sure if we support windows

[pseudo-rnd-thoughts]

However, I am not sure if we support windows

Yes, is the simplest solution and Gymnasium doesn't officially support windows.
Our general rule has been if we can make simple changes to support windows then we will otherwise no

[Misteridk2022]

So far, I've tried pip install stable-retro --pre, pip3 install stable-retro, and pip install stable-retro --use-pep517 with no luck. still showing the error.

You can use WSL2 (Windows sur Subsystem for Linux) on Windows with Ubuntu 22.04 virtual machine and install stable-retro in the VM. It's works quite well and will be much less painful than running directly on Windows.

Here is a simple video for that:
