安装nokogiri时出错（1.5.2）
当我尝试在rails项目上运行ruby时出现错误：
An error occurred while installing nokogiri (1.5.2), and bundle cannot continue. Make sure that 'gem install nokogiri -v 1.5.2 succeed before building. 我正在研究Ubuntu 10.10
我的同事在Windows / RVM上使用并没有这个问题。

从输出：

安装libiconv。
没有必要安装任何附加包。 您可以使用包含BitNami的库（在/ opt / bitnami / common中）。 您只需加载BitNami环境并指定libxml2文件的路径。 在测试时我得到了类似的问题，但是对于libxml2，类似的解决方案可以应用于您正在接收的iconv错误。
$/opt/bitnami/rubyconsole $sudo gem install nokogiri -- --with-xml2-dir=/opt/bitnami/common --with-xml2-include=/opt/bitnami/common/include/libxml2 Building native extensions. This could take a while... Successfully installed nokogiri-1.5.2 1 gem installed Installing ri documentation for nokogiri-1.5.2... Installing RDoc documentation for nokogiri-1.5.2...
安装系统软件包并使用它们的解决方案也应该有效。
nokogiri要求
sudo apt-get install libxslt-dev libxml2-dev
sudo gem install nokogiri

什么对我有用（Mac OS X）：
$ xcode-select --install
