Due to recent changes by YouTube, yt-dlp now requires Deno (not Denort) to be installed in order to download YouTube videos in maximum quality. If you don't plan on downloading youtube videos, or don't care about video quality, you can ignore this tutorial:
Windows users should run powershell "irm https://deno.land/install.ps1 | iex". If that fails, run powershell "irm https://deno.com/install.ps1 | iex". If that also fails, run powershell "irm https://deno.land/x/install/install.ps1 | iex".
MacOS and Linux users should run curl -fsSL https://deno.land/install.sh | sh. If that fails, use curl -fsSL https://deno.land/x/install/install.sh | sh
