由于nokogiri gem，无法安装capybara

Question

i attached capybara to my Gemfile. when i bundle install, i always get this message

Gem files will remain installed in /Library/Ruby/Gems/2.0.0/gems/nokogiri-1.6.3.1 for inspection. Results logged to /Library/Ruby/Gems/2.0.0/extensions/universal-darwin-13/2.0.0/nokogiri-1.6.3.1/gem_make.out 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 realized that the problem with nokogiri gem, but i googled all the available methods to install it and that giving me the same output.

i wanna get the point of that error because a similar ones occurs frequently.

Solved, you need to reinstall libiconv even if it's already installed because it may be missed or corrupted . then you can install nokogiri.

brew tap homebrew/dupes.

brew install libiconv.

brew link libiconv --force.

gem install nokogiri -v 1.6.3.1 -- --with-iconv-dir=/usr/local.
