Ruby update 1.8.7 to 1.9.3

Question

When I look at the version of Ruby

`$ ruby -v`

i get

ruby 1.8.7 (2011-06-30 patchlevel 352) [x86_64-linux]

but when I want to upgrade Ruby

$ rvm install 1.9.3

i get

Already installed ruby-1.9.3-p194.

What's the problem?

Thanks all!

ruby version selected by the rvm is depending on which version of rvm you are using.

Try following

   rvm use 1.9.3
   ruby -v

To find all the installed versions of ruby use following

   rvm list

I'm tried, but get a error: RVM is not a function, selecting rubies with 'rvm use ...' will not work. – Ray Smith Sep 19 '12 at 11:39

I don't see any problem.

The version that you told RVM to use is 1.8.7, and you also have a 1.9.3 installed that you could tell RVM to use if you wanted to.
