chruby and ruby not available when I use sudo

Question

I have installed chruby on ubuntu 14.04 and installed ruby-install and installed ruby 2.1.1 into /opt/rubies/

I have put the following into /etc/profile.d/chruby.sh

if [ -n "$BASH_VERSION" ] || [ -n "$ZSH_VERSION" ]; then
  source /usr/local/share/chruby/chruby.sh
  chruby ruby-2.1.2
fi

I want all users to use that ruby and there is no default ruby package installed.

If I do chruby logged in as myself I get:

ubuntuserver ~: chruby
 * ruby-2.1.2

And ruby -v gives:

ubuntuserver ~: ruby -v
ruby 2.1.2p95 (2014-05-08 revision 45877) [i686-linux]

However if I do sudo chruby I get:

sudo: chruby: command not found

And if I do something like sudo rmate myfile.txt I get:

ubuntuserver ~: sudo rmate test.txt

/usr/bin/env: ruby: No such file or directory

I want to know how to make that ruby universal to users sessions jobs webserver etc.

This question appears to have been answered on the chruby wiki

In essence you would have to get a root prompt and then run the chruby setup script , switch rubies then run your command ..

Alternatively you can use sudo chruby-exec ruby-n.n.n -- [command]

eg. If I run

sudo chruby-exec ruby-2.1.2 -- rmate test.txt

it does invoke textmate as required.
