If you installed rbenv and ruby-build with homebrew and when you do echo $(rbenv root), you get /usr/local/var/rbenv instead of /Users//.rbenv, here is how to fix the issue.

When you install rbenv with homebrew, homebrew says:

To use Homebrew's directories rather than ~/.rbenv add to your profile:
export RBENV_ROOT=/usr/local/var/rbenv

Don't do that. Remove that line from your profile. Make sure you refresh your terminal after.

Then remove any signs of rbenv in the /usr/local/var directory:

sudo rm -r /usr/local/var/rbenv

Now when I do echo $(rbenv root) I get /Users//.rbenv instead of /usr/local/var/rbenv.

That fixed it for me.
