I tried to uninstall and reinstall Nokogir again, with the same result.

I think RubyGems didn't download the file properly. So, the system is reporting that the gem is corrupt.
Delete /home/tarek/.rvm/rubies/ruby-2.1.2/lib/ruby/gems/2.1.0/cache/nokogiri-1.6.4.1.gem and then install the gem again.
$ sudo rm /home/tarek/.rvm/rubies/ruby-2.1.2/lib/ruby/gems/2.1.0/cache/nokogiri-1.6.4.1.gem
$ gem install nokogiri
Please make sure you install the following command:
sudo apt-get install libxslt-dev libxml2-dev
Now try installing Nokogiri. Be aware of sudo if you using RVM.
sudo gem install nokogiri
Hope my answer would be helpful.
Thanks.
Looks like you have the system Ruby installed.
You need to first do:
$ sudo apt-get install ruby-dev
and then do:
$ sudo gem install nokogiri
I'd encourage you to use Ruby Version Manager like RVM or rbenv for managing Ruby environments instead of using the system Ruby on your development environment.

What should i do to solve this problem?
It looks like your source either isn't responding properly or the gem can't be found at the source.
Try gem install rack-test. If that gives you an error try switching the source you're getting the gem from.
First add the source
gem source -a 'https://production.cf.rubygems.org'
Then try installing again.
OR
You could try installing directly from a different source with
gem install rack-test --source 'https://production.cf.rubygems.org'
Once you get that gem to install properly, try installing rails again.

mkmf is part of the ruby1.9.1-dev package. This package contains the header files needed for extension libraries for Ruby 1.9.1. You need to install the ruby1.9.1-dev package by doing:
sudo apt-get install ruby1.9.1-dev
Then you can install Rails as per normal.
Generally it's easier to just do:
sudo apt-get install ruby-dev
The suggested answer only works for certain versions of ruby. Some commenters suggest using ruby-dev; that didn't work for me either.
sudo apt-get install ruby-all-dev
worked for me.
sudo apt-get install ruby-dev
worked for me

I've had a similar error when trying to install rails. The issue was that I had not installed the ruby-devel.i686 bundle. Granted this is on CentOS 6.3, but it seems like you may need to install this as well.
