Question

I’m trying to setup a second ruby install in my home directory (a different version of ruby for testing). I’ve compiled ruby into ~/bin/ and everything is working until I try to install rubygems.

I have GEM_HOME set to ~/gems directory and GEM_PATH set to the same. Then I try to install rubygems with

~/bin/ruby setup.rb 

The installation appears to succeed but ruby can’t find rubygems after the install.

$~/bin/irb irb(main):001:0> require 'rubygems' LoadError: no such file to load -- rubygems     from (irb):1:in `require'     from (irb):1 

Anyone have any idea why ruby can’t find rubygems?

In addition to setting GEM_HOME you need to run config with your path. Here are the steps from rubygems.org.

$ export GEM_HOME=/home/mygemrepository $ ruby setup.rb config --prefix=/home/mystuff $ ruby setup.rb setup $ ruby setup.rb install
