Update effect on installed Ruby versions.

[k-brummer]

Hi,

I'm currently running an older version of rbenv on my production server and I would like to upgrade it to use ruby 3.
I'm wondering if I upgrade rbenv, will it override my current versions of ruby installed. Or will my old versions still be installed.
I still want to use the old versions and don't want my rails on my server to crash.

Any help would be appreciated!

The short answer is that upgrading rbenv itself should have no impact on the versions of ruby that are installed. Rubies live under $(rbenv root)/versions (see RBENV_ROOT under Environment Variables in readme)

Rbenv itself can live anywhere, with its bin/ directory added to PATH. If you installed rbenv via git clone, then simply pulling would only update rbenv's installation directory. If you installed via a package manager, like homebrew, then it can be upgraded with the package manager and again would only affect rbenv's installation itself.
