Unable to install nokogiri using rvm, receiving "nokogiri requires Ruby version >= 1.9.2"

Question

If I try to install nokogiri, I receive the following error:

rvmsudo gem install nokogiri
ERROR:  Error installing nokogiri:
    nokogiri requires Ruby version >= 1.9.2.

If I check my ruby version, it tells me I am running ruby1.9.3

ruby -v
ruby 1.9.3p448 (2013-06-27 revision 41675) [i686-linux]

If I use printenv, these are my env variables:

I have some pretty bad luck with RVM and rather than break my entire installation, I thought I'd ask here.

Why can't I proceed with the installation of nokogiri?

I'm on Debian.

Just try gem install nokogiri as you have RVM installed. See here Installing Nokogiri for other things to install with it.

Like below :

# nokogiri requirements
sudo apt-get install libxslt-dev libxml2-dev
gem install nokogiri
