rbenv (Simple Ruby Version Management) lets you easily switch between multiple versions of Ruby. It's simple, unobtrusive, and follows the UNIX tradition of single-purpose tools that do one thing well.

Another tool to be used for the same purpose is RVM.


You can install rbenvAUR from the AUR.


rbenv can be extended via a plugin system, and the rbenv wiki includes a list of useful plugins. The ruby-build plugin is especially useful, as it allows you to install Ruby versions with the rbenv install command. You can install ruby-buildAUR from the AUR.


Ruby 2.3.x

Installation of Ruby 2.3.x may break down due to openssl version and/or segmentation fault error while compilation. Both errors are described here:

 ossl_ssl.c:465:38: error: ‘CRYPTO_LOCK_SSL_SESSION’ undeclared
 make: *** [uncommon.mk:655: enc.mk] Aborted (core dumped)

Here's a way how you can make a ruby compile:

1. Install gcc-5 and openssl-1.0 packages first:

 sudo pacman -Syyu openssl-1.0 gcc5

2. Then run:

 CC=/usr/bin/gcc-5 \
 PKG_CONFIG_PATH=/usr/lib/openssl-1.0/pkgconfig \
 rbenv install 2.3.4

Ruby 2.x.x

Installation of Ruby 2.0.0, 2.1.4, 2.1.6, 2.1.7, 2.2.2 and 2.2.3 may show this error

 ossl_ssl.c:141:27: error: ‘SSLv3_method’ undeclared here (not in a function)

This can be solved using the patch as described here

 curl -fsSL https://gist.github.com/mislav/055441129184a1512bb5.txt | PKG_CONFIG_PATH=/usr/lib/openssl-1.0/pkgconfig rbenv install --patch 2.2.3

Ruby 1.9.3

Installation of Ruby 1.9.3 may show the same error:

 ossl_ssl.c:116:27: error: ‘SSLv3_method’ undeclared here (not in a function)

This can be solved by using the patch as described here

 curl -fsSL https://gist.githubusercontent.com/anonymous/679228bc324d6fdd3074.txt | rbenv install --patch 1.9.3-p448
