Rails和Ubuntu报告不同的ruby版本

Question

I use Vagrant and Chef to create new servers when I am developing. I want to start out on Ruby on Rails so I am setting up a server. Everything is working but Ubuntu and Rails are reporting different Ruby versions.

Ubuntu 12.04: ruby -v = ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-linux]
Rails = 1.8.7 (x86_64-linux)

I don't want Ruby 1.8.7 on the system at all but I can't get rid of it. Is there anyway to set a default Ruby version?

I don't want top use RVM or similar.

Answer 1

try this aptitude purge ruby

and then install the latest version or the version you want

came across this post in stackoverflow How do I make Ruby 1.9 the default Ruby on Ubuntu?

Answer 2

This did the trick.
