当我尝试运行ruby on rails项目时，我遇到了一个错误：
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.
我在Ubuntu 10.10 上工作
我的同事在Windows/RVM上使用，没有这个问题。

libiconv is missing. please visit http://nokogiri.org/tutorials/installing_nokogiri.html for help with installing dependencies.

来自输出：

安装libiconv。
nokogiri要求
sudo apt-get install libxslt dev libxml2 dev
sudo gem安装nokogiri
您可以访问http://nokogiri.org/tutorials/installing_nokogiri.html
不需要安装任何附加软件包。您可以将库includes与BitNami一起使用（在/opt/BitNami/common中）。您只需要加载BitNami环境并指定libxml2文件的路径。在测试时，我遇到了类似的问题，但使用libxml2，可以对您收到的iconv错误应用类似的解决方案。
$/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...

安装系统包并使用它们的解决方案也应该有效。
什么对我有效（Mac OS X）：
$ xcode-select --install
