How do you uninstall rbenv on macOS?

I took these steps to successfully get rid of rbenv on my mac running El Capitan (10.11.4). Rbenv is a major cause of Failed to build gem native extension errors from my experience.

• Remove using brew: brew remove rbenv
• Delete .rbenv directory: rm -rf ~/.rbenv

For Bash

• Open .bash_profile file and delete any lines with rbenv in them: vi ~/.bash_profile
• Open .bashrc file and delete any lines with rbenv in them: vi ~/.bashrc

Finally, reload .bash_profile and .bashrc:

. ~/.bash_profile && . ~/.bashrc

For ZShell

• Open .zprofile file and delete any lines with rbenv in them
• Open .zshrc file and delete any lines with rbenv in them

Finally, reload .zprofile and .zshrc:

. ~/.zprofile && . ~/.zshrc
