Having trouble installing Rspec - ruby

Question

So this is my first time asking a question here, so please bear with me. For the past few DAYS I've been trying to install rspec onto my system. After an introductory project a couple of months ago I became familiar with the fact that my Mac has ruby installed and it won't let me really install any gems as it would reply with a permissions denied notice. So I installed ruby from homebrew and went about my coding. Now present day I want to install rspec following a walkthrough I'm working on but the system won't let me. I've looked online and I thought it was my PATH and even tried changing it multiple times and it wouldn't work. At one point my terminal wouldn't even read the entirety of my bash_profile even though I source'd the file more than once. I've since updated to zsh and it's the exact same thing.
