This is an unfortunate error from github.com/creack/pty, which doesn't seem to support Windows:

Looks like there's an open PR for Windows support for Pty. If this is time sensitive, you might be better off building VHS from source and adjusting the dependency to use the upstream that supports Windows. Hopefully that all gets resolved on our upstream soon, but as it involves breaking changes to their API, I can understand why it is taking a while to consider.

https://github.com/creack/pty/pull/155

I'll talk to the team about what can be done on our end to support Windows users without breaking our project 😅

sounds great! thanks !

Would it make sense to add a warning on Windows to this section? It's a bit jarring and has turned my off to using VHS in the past.

terminal, err := pty.Start(command) 
 if err != nil { 
        if runtime.GOOS == "windows" {
                log.Warnf("Windows dependency pty : %q\n", err)
        }
        return err 
 } 

With the progress on this issue (about an update a month) it doesn't seem like this will be quickly resolved. The last comment is a reference to a PR on the Go Gerrit to add support for Window's PsudoConsole Syscall. No response on the parent issue regarding this, plus depending on if we're in a Go feature freeze we might have a few months to wait regardless if this new SysCall is Pty's solution not counting the time for Pty to finish their tests. Current tests are still failing on Linux according to their CI.

@tristanisham that's a good idea, I think it would be worth adding
