MPV + Sponsorblock does not see Python, how to show path?

Question

Debian

I use an mpv player on debian (and on windows too ..) I put the lua script "sponsorblock" and it writes on the player's console that it cannot find / read the python directory that is in the system. And it used to happen with yt-dlp, there was some kind of command for the console, showing a directory or something. But it didn't seem to help and I forgot already.
Question: What to prescribe / can reinstall python (?) so that the script sees it.
