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.

Installation

You can install rbenvAUR from the AUR.

Plugins

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.

Troubleshooting

Ruby 2.3.x

Before compiling, make sure you have all the dependencies needed:

 pacman -S --needed gcc6 base-devel libffi libyaml openssl zlib

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-6 and openssl-1.0 packages first:

 sudo pacman -Syyu openssl-1.0 gcc6

2. Then run:

 CC=/usr/bin/gcc-6 \
 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

If above was not enough you can install openssl-1.0 and gcc6 and try:

 curl -fsSL https://gist.githubusercontent.com/anonymous/679228bc324d6fdd3074.txt | CC=/usr/bin/gcc-6 PKG_CONFIG_PATH=/usr/lib/openssl-1.0/pkgconfig rbenv install --patch 1.9.3-p551
