Installing Deno with npm on Windows doesn't work (don't do it!) #15043
Description
Checklist
- I'm reporting a bug unrelated to a specific site
- I've verified that I have updated yt-dlp to nightly or master (update instructions)
- I've searched known issues, the FAQ, and the bugtracker for similar issues including closed ones. DO NOT post duplicates
- I've read the policy against AI/LLM contributions and understand I may be blocked from the repository if it is violated
Provide a description that is worded well enough to be understood
I installed Deno but it doesn't seem to be able to see it.
Provide verbose output that clearly demonstrates the problem
- Run your yt-dlp command with -vU flag added (
yt-dlp -vU <your command line>) - If using API, add
'verbose': TruetoYoutubeDLparams instead - Copy the WHOLE output (starting with
[debug] Command-line config) and insert it below
