Error occurring while following ODOT series

Ok, so I am following along with ODOT series and I am on video 2 "Set up Git and Add Gems". The problem I am having is after I add this to my gem file:

group :development, :test do
  gem 'rspec-rails', '~> 2.0'
end

group :test do
  gem 'capybara', '~> 2.1.0'
end

And then run bundle in my terminal, I get the following error:

An error occurred while installing nokogiri (1.6.3.1), and Bundler cannot continue. Make sure that `gem install nokogiri -v '1.6.3.1'` succeeds before bundling.

Here is the complete output in my terminal:

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

Do just that - in your terminal write gem install nokogiri -v '1.6.3.1' , wait for it to finish installing and then try bundle install again.

OR change the RSpec gem version to 2.14, maybe this would help (don't do version 3, since it has some changes in the syntax)..

I tried that but I am still getting the same error.

I also tried changing the RSpec gem:

gem 'rspec-rails', '~> 2.14'

OK, try newer version of RSpec (2.14) and newest capybara ('~> 2.4.1') - just chang ethos enumbers in the gemfile and run bundle install..

Also, are you, by any chance, using Vagrant?

I am not using Vagrant. Not even sure what it is...

I also tried changing the versions and running bundle install but that didn't work either.

OK, what operating system are you on? Does bundle work when you remove rspec or capybara from gemfile?

I am running a Mac OS X 10.7.5

Bundle works and I no longer get an error after I remove capybara gem

I don't know if these means anything but, when I ran my first bundle (before adding those two gems) I got this output in my terminal

Guess not since I just updated my RubyGems and still the same error. :(

Did you try doing these things from the links? Especially the first one and the second one?

Hi Maciej,

I did but still no luck. I posted another question similar to this one earlier that is a little different and may be helpful. https://teamtreehouse.com/forum/trouble-installing-nokogiri-odot-series

Thanks for all your help you deserve an award!
