I was NEVER able to install torrentio :/ Any advice?

I'm sick of this (っ °Д °;)っ Every time I try to install it, I get an error and I can't do it (I've been trying to install it for a year). The only thing that's working for me is the "Media Fusion ElfHosted" add-on (although some series don't even appear there, for example, "Shameless")
