Well...

1. The "Readline raku module" expects "GNU Readline" to be installed, which is more than unusual on Windows.
2. Star installs a set of modules, the same modules on Linux and Windows.

Thanks for reporting...

1. Star installs a set of modules, same modules on Linux and Windows.
2. The "Readline raku module" expects "GNU Readline" to be installed on the client, which is more than unusual on Windows.

I'm not sure how to tackle such issues in general.
You can either ignore this message (as the fallback works ;) ), de-install the "Readline" module or get the readline.dll [1] somehow on your system where RAKU will find it.

[1] - The readline.dll would have to be build / compiled with the same tool chais as RAKU itself was build, so for the Windows versions of Rakudo and Star, this is currently MSVC... right now, I would only be aware of KeePassXC, which brings a perfect fitting readline.dll along...

Just FYI. I'm soon starting to work on getting all of the native Raku Terminal stack working on Windows. This will include Terminal-ReadLine. Currently it's mostly NYI everywhere. Lately Windows natively supports terminal escape sequences. It does not support the surrounding C APIs like termios. A start should be: https://todo.sr.ht/~patrickb/Terminal-MakeRaw/1.
