As I know,
ruby -e 'puts RUBY_VERSION'
will print out ruby version. In Ubuntu 14.04, they will print
1.9.3
but its libraries path is
/usr/lib/ruby/1.9.1
- Why are they different?
- How can I get the latter one?

If you were able to get the latter one (library path), why are you asking how to get it? – sawa Sep 15 '15 at 08:59

I want to get it from command line or program. – Like Sep 15 '15 at 10:10

Why are they different?
Because compatible Ruby versions (often (but not always) within the same major version) share the libraries. Ruby 1.9.3 share the libraries with 1.9.1.
How can I get the latter one?
$LOAD_PATHor
Gem.default_path

Is there any way to get the compatible version directly, just like 1.9.1? – Like Sep 15 '15 at 11:49
