如何安裝Nokogiri？

我安裝了所有庫（linux），但它不會工作，爲什麼？如何安裝Nokogiri？

gem install nokogiri -- --with-xml2-include=/home/mka/.linuxbrew/Cellar/libxml2/2.9.2/include/libxml2 --with-xml2-lib=/home/mka/.linuxbrew/Cellar/libxml2/2.9.2/lib --with-xslt-dir=/home/mka/.linuxbrew/Cellar/libxslt/1.1.28_1 --with-iconv-include=/home/mka/.linuxbrew/Cellar/libiconv/1.14/include --with-iconv-lib=/home/mka/.linuxbrew/Cellar/libiconv/1.14/lib

This could take a while...

請問我該如何解決這個問題？

無法加載這樣的文件 - OpenSSL的（LoadError） –

「檢查有關詳細信息，mkmf.log文件」你這樣做呢？ – Meier

@Meier，我無法找到，我搜索這個位置：〜/ .gem/gems/nokogiri-1.6.6.2/ext/nokogiri – Freeman

嘗試使用：gem install nokogiri -- --use-system-libraries

謝謝，但我測試之前，它顯示關於「libxml2」的錯誤... – Freeman

歡迎堆棧溢出。不要使用「源」這樣的錨文本創建鏈接，而要提供鏈接目標的摘要，例如頁面的標題。這有助於人們知道它們在哪裏服用。 –
