debian 13.1, yt-dlp stable@2025.11.12 from yt-dlp/yt-dlp, updated with yt-dlp -U
I also installed deno on the terminal with curl -fsSL https://deno.land/install.sh | sh
however, nothing happens if I execute yt-dlp, like: yt-dlp --all-subs --no-warnings https://www.youtube.com/watch?v=1bhuN9nqEb4 returns nothing.
All my terminal shows after executing a command like the one pasted I get:
>
that’s it, a > and nothing else.
Am I doing something wrong?


Semi-related for people whose distros don’t package deno, I installed deno in a distrobox and exported it with
distrobox-exportand yt-dlp picked it up just fine from my $PATH. Before I did so, running yt-dlp gave the following error:WARNING: [youtube] No supported JavaScript runtime could be found. YouTube extraction without a JS runtime has been deprecated, and some formats may be missing. See https://github.com/yt-dlp/yt-dlp/wiki/EJS for details on installing one. To silence this warning, you can use --extractor-args "youtube:player_client=default"
