I am trying to start a rails server, but I keep receiving a lengthy and cryptic error message saying that I have an incompatible library version for nokogiri 1.6.8. I have looked at other similar solutions about libxml2, libxslt, and libiconv not been linked with nokogiri and I have tried the what people recommend to fix that, but I still receive the message:

Remove the Gemfile.lock in the root directory of the application. Then, remove the versions written in the Gemfile, just have the name of the gem there. Then, again do bundle install. Maybe this can help.
I just started learning rails and I am currently learning through the Lynda course Ruby on Rails 3 Essential Training with Kevin Skoglund. At the point that I have reached, we are trying to build our first web app and we are instructed to create our server by typing rails server which as you can see I did. When I type that, that whole loading error mess appears and I have no idea how to fix it.

make sure your Gemfile contain:
gem 'nokogiri'
then run bundle install command, try run rails s if you still get the same error restart your machine to make sure gemset updated.
if the problem still occur edit agian your Gemfile and put:
gem 'nokogiri', :require => false
run bundle install and try run rails s.
edit
Just noticed you are Windows user and use ruby 2.2 which nokogiri isn't compiled yet for your env, sorry:
https://github.com/sparklemotion/nokogiri/issues/1256

Try updating Rails to version 4.2.10 or later.
At least the method Rails::Railtie::Configuration#eager_load_namespaces is defined railties-4.2.10.
As soon as I try to start rails server I encounter following problem. Can anybody please help.
