Warning: The cleaning step did not complete successfully
Still, the installation was successful, so we will link it into your prefix
==> Caveats
To enable shims and autocompletion add to your profile:
  if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi

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