how to switch between the same version of ruby

[mikeni]

I installed two versions of the same ruby version

1.)
ruby-install ruby 2.2.0

Successfully installed ruby 2.2.0 into /home/mike/.rubies/ruby-2.2.0

2.)
cd /home/mike/manual_install_ruby-install_sudo/ruby-install-0.5.0/bin
sudo ./ruby-install ruby 2.2.0

Successfully installed ruby 2.2.0 into /opt/rubies/ruby-2.2.0

when i run the "chruby" command, I get
chruby

• ruby-2.2.0
  ruby-2.2.0

the reason for this is because,
for a.) I use the ruby to load the passenger gem to install passenger/nginx for web server purposes

for b.) I want a ruby with gems specific for the user

when i run "chruby ruby-2.2.0", I always end up with the ruby installed into /opt/rubies/ruby-2.2.0

is there anyway to choose between the two?

ok after reading the chruby.sh file, i see that it iterates through the RUBIES and breaks as soon as it finds a match

I guess if I have installed rubies in both /opt/rubies and ~/.rubies , then I should write a custom chruby.sh where I switch the order like, the following below, to have priority with local rubies?

for dir in "$HOME/.rubies" "$PREFIX/opt/rubies"; do
[[ -d "$dir" && -n "$(ls -A "$dir")" ]] && RUBIES+=("$dir"/*)
done
unset dir

Sounds reasonable to search $RUBIES in reverse order.
