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!

Answer 1

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
