安裝 nokogiri 失敗時的解決方法

(參考此篇文章)[https://github.com/sparklemotion/nokogiri/issues/1483] 在 bash 輸入 xcode-select --install 可解決問題。 在我的 macbook 上的錯誤訊息如下: ``` Gem::Ext::BuildError: ERROR: Failed to build gem native extension. current directory: /Users/etrex/.rvm/gems/ruby-2.4.1@-global/gems/nokogiri-1.8.0/ext/nokogiri /Users/etrex/.rvm/rubies/ruby-2.4.1/bin/ruby -r ./siteconf20171011-80748-pgpdll.rb extconf.rb checking if the C compiler accepts ... yes checking if the C compiler accepts -Wno-error=unused-command-line-argument-hard-error-in-future... no Building nokogiri using packaged libraries.
