This is an annoying problem but usually fairly easily remedied! Like jc
said above, it's likely because your rbenv or rvm files are no longer
loaded when you start your shell.

First thing to do is figure out which shell you actually use. Type this
into your terminal:

$0

That'll tell you which shell you use. It'll likely return zsh given that
you had a zshrc file.

>From here just do what jc said, and reinstall rbenv.. (or rvm, whichever
you used); Make sure during the installation (if you're using zsh) that you
change the copy paste install paths from bashrc to zshrc, for example:

Change from:

*echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile*

To

*echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.zshrc*

In the install instructions.

This also answers your other question about why you also had a bashrc! I
expect at some point you may have copy paste installed something which
created and appended to your bashrc, but then was never used. I'd be very
surprised if your system was somehow dynamically switching between shells.

If you're using zshrc, also consider reinstalling oh-my-zsh. This will
restore some of your (probably) lost functionality.

It's very useful to keep all of your dot files in an git repo, I have one
dedicated to tmux, zsh, vimrc etc - any changes I make I immediately push.

Hope this helps.
