我不小心刪除了一些庫（我想，不要問怎麼）。現在我無法安裝我需要的nokogiri版本。我已閱讀其他類似問題的帖子，他們的解決方案並沒有幫助。請看下面的錯誤:(捆綁安裝特定的nokogiri -v'1.6.1'問題

*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers. Check the mkmf.log file for more details.

An error occurred while installing nokogiri (1.6.1), and Bundler cannot continue.
Make sure that `gem install nokogiri -v '1.6.1'` succeeds before bundling.
我已經試過釀安裝libxml2的一些配置選項，試圖與庫等安裝在世界那會是什麼？
獲得nokogiri及其依賴工作可能會變得乏味。對於初學者，請告訴我們您的操作系統以幫助您找到庫 – mlabarca
例如，在我的Mac上，使用el Capitan，我必須執行'brew install libxml2 libxslt'來安裝系統庫，然後使用bundler'bundle config build.nokogiri - -use-system-libraries = true --with-xml2-include =/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/libxml2' For更多信息看看http://www.nokogiri.org/tutorials/installing_nokogiri.html – mlabarca
