I'm working on Michael Hartl's RoR tutorials. I'm on chapter 3. Unfortunately, copy and pasting the gem files won't work for me, but I figured out which gem is the problem. It's the capybara gem. I've commented it out and continued the tutorial, but I'm at the point where I need to use the gem.
Here is an example $bundle update giving me an error:
$ bundle update

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.
I tried going to the nokogiri website and fixing the problem, but when I try to update the missing libraries (an earlier part of the error), my machine says I already have them.
Here is my Gemfile:
source 'https://rubygems.org'
ruby '2.0.0'
#ruby-gemset=railstutorial_rails_4_0
gem 'rails', '4.0.8'
group :development, :test do
gem 'sqlite3', '1.3.8'
gem 'rspec-rails', '2.13.1'
end
group :test do
gem 'selenium-webdriver', '2.35.1'
#gem 'capybara', '2.1.0' # This line breaks everything
end
gem 'sass-rails', '4.0.1'
gem 'uglifier', '2.1.1'
gem 'coffee-rails', '4.0.1'
gem 'jquery-rails', '3.0.4'
gem 'turbolinks', '1.1.1'
gem 'jbuilder', '1.0.2'
group :doc do
gem 'sdoc', '0.3.20', require: false
end
group :production do
gem 'pg', '0.15.1'
gem 'rails_12factor', '0.0.2'
end
EDIT: From the http://nokogiri.org/tutorials/installing_nokogiri.html install page
I followed all of the steps and at the final step where I need to run the command
gem install nokogiri -- --with-xml2-include=/usr/local/Cellar/libxml2/2.7.8/include/libxml2
--with-xml2-lib=/usr/local/Cellar/libxml2/2.7.8/lib
--with-xslt-dir=/usr/local/Cellar/libxslt/1.1.26
--with-iconv-include=/usr/local/Cellar/libiconv/1.13.1/include
--with-iconv-lib=/usr/local/Cellar/libiconv/1.13.1/lib
The output from my console is:
