ruby -v says no such file or directory in mac os

I had the original ruby v2.6.8 I believe on my mac os. I wanted to upgrade to ruby 3.1.2 to get access to rails.

I installed ruby via homebrew, however I decided it woud be easier to manage using rbenv. I went to uninstall ruby via homebrew, and then instaled ruby 3.1.2 with rbenv.

Now when I use the

ruby -v 
-bash: /usr/local/opt/ruby/bin/ruby: No such file or directory

using the command which ruby brings me this:

/Users/user/.rbenv/shims/ruby

So the ruby is there, and rbenv claims it installed ruby 3.1.2, but did homebrew install all of ruby including the version osx came with? Im pretty sure thats a yikes moment if it did. I also can't use any ruby commands under these circumstances so I don't really know what to do from here?

How do I get my $PATH to recognize the rbenv path to ruby as the global path? I'm on MacOs 11.3.1 BigSur if thats relevant.
