An error occurred while installing nokogiri (1.6.7), and Bundler cannot continue.
Make sure that `gem install nokogiri -v '1.6.7'` succeeds before bundling.
按照“Failing to install Nokogiri gem”中的建议，我尝试运行失败：
bundle config build.nokogiri --use-system-libraries
bundle install
按照“Failing to install Nokogiri gem”中的建议，我也尝试过：
gem install nokogiri -- --use-system-libraries
和：
gem install nokogiri -v 1.6.5 -- --use-system-libraries
我的操作系统版本是 El Capitan 10.11.2，并且我检查了 Xcode 许可协议是否已被接受。
任何想法如何让 Nokogiri 安装成功？
