I've completely uninstalled and re-installed rbenv & ruby 2.5.3. Any ideas why this is still failing?

Same. I'm running Arch Linux and Ruby 2.6.0-preview2 though.

Duplicate of #118, fixed by #120

I'm sorry for the inconvenience with my wrong packaging.
I've released the version 1.4.1 with #120.
Please retry with the new version.

All good @mrkn. It happens. Thanks for fixing.
