From 050caead5475e62a74b41bd4cef5759b13bf04d1 Mon Sep 17 00:00:00 2001 From: Mattias Tall Date: Tue, 26 May 2026 10:16:10 +0200 Subject: [PATCH] Install Node.js via nodeenv (pip); use web client MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit nodeenv is a Python package that downloads a pre-built Node.js binary — no apt repos, no compilation, guaranteed to work in python:3.12-slim. The 'node' binary is linked into /usr/local/bin so yt-dlp can find it. With Node.js available the web client works fully (37 formats) and can solve YouTube's n-challenge that every other approach was failing on.
