Installation errors

[emminz]

I’m getting errors when installing Magic Mirror. I had a lot more but was able to google my way through most of them and here’s what I can’t figure out:

Installing dependencies …

This is my first real Pi project so I’m not really sure what it’s telling me. I attempted an install previous to this and got a ton more errors. I did an npm update or something and it took care of most of them but this is what’s left. I’, installing on a Pi3B+.

Thoughts?

Thanks
