hypeScrapper v4 activation error in elgg 1.12

[VladVuk]

Hello,

I would like to provide user with ability to insert iframe framed link to youtube video through CKEditor (for users custom pages).
I need that features for Elgg 1.12.4 and Elgg 2.3.
As I see Elgg deletes each iframe based html text when user tries to save the page.

So I tought that hypeScraper might be the solution.
I downloaded the hypescraper (v4) and hypeapps (v4) from github and unzipped them and activated plugins in my Elgg v1.12 and received following errors:

Can you explain what I have to do more to get it work?

I am not familiar with Composer so please explain it in a way that I can do it.

Thanks,
