An error occurred while installing nokogiri (1.7.1), and Bundler cannot continue.
Make sure that `gem install nokogiri -v '1.7.1'` succeeds before bundling.
run bundle exec spring binstub --all
Could not find gem 'coffee-rails (~> 4.2)' in any of the gem sources listed in your Gemfile or available on this machine.
Run `bundle install` to install missing gems.
It seems the error is due to failure of installing Nokogiri, I've tried the solutions from here. None of them works.
