ruby-on-rails - Rails and Ubuntu reporting different ruby versions

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

これを試してaptitude purge ruby

次に、最新バージョンまたは必要なバージョンをインストールします

stackoverflowでこの投稿に出くわしましたRuby1.9 をUbuntuのデフォルトのRubyにするにはどうすればよいですか？
