uninstall ruby version from rbenv

Question

How to uninstall or remove ruby version from rbenv. I have installed two versions of ruby. While switching to ruby 1.9.3, I am getting segmentation fault. Can anyone please help

Answer 1

New way

Use the uninstall command: rbenv uninstall [-f|--force]

rbenv uninstall 2.1.0  # Uninstall Ruby 2.1.0

Use rbenv versions to see which versions you have installed.

Old way

To remove a Ruby version from rbenv, delete the corresponding directory in ~/.rbenv/versions. E.g.

rm -rf ~/.rbenv/versions/1.9.3-p0

Run rbenv rehash afterwards to clean up any stale shimmed binaries from the removed version.
