Can't install Ruby on Rails Ubuntu

Question

I'm trying to install Ruby on Rails on Ubuntu. was using a tutorial but it didn't work.

It may be out of date I don't know. I wish to use RVM and a Postgres db. Yarn seems to install correctly. yarn -v When I look at the version number I see yarn is installed. But when I try to run Ruby on Rails I get 'switch to trollop' instead of yarn. I haven't a clue what trollop is but I presume it's a version manager. Unfortunately it doesn't say how to switch to it. And does trollop work with Ruby on Rails Any help would be greatly appreciated. Thanks,
