WARNING: [youtube] [jsc] Remote components challenge solver script (deno) and NPM package (deno) were skipped. These may be required to solve JS challenges. You can enable these downloads with --remote-components ejs:github (recommended) or --remote-components ejs:npm , respectively.

Providing one of the flags automatically lets it automatically get what it needs. No need for AUR packages :)Edit: Maybe I misunderstood, now when I re-read your post. You meant it'll prevent the automatic download at runtime perhaps? That sounds about right if so.
