The file "/usr/include/iconv.h" is missing in your build environment,
which means you haven't installed Xcode Command Line Tools properly.

To install Command Line Tools, try running `xcode-select --install` on
terminal and follow the instructions.  If it fails, open Xcode.app,
select from the menu "Xcode" - "Open Developer Tool" - "More Developer
Tools" to open the developer site, download the installer for your OS
version and run it.

我在几个系统配置中遇到过这种情况。它最终总是成为开发人员库的依赖项。如果是我，我会一次安装一个，然后尝试捆绑安装：
libxslt-dev
libxml2-dev
ruby-dev

取决于您的系统（我认为在centos上它们是-devel而不是-dev）。
此命令：
sudo gem安装nokogiri--with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include/libxml2--使用系统库

找到了，解决了我的问题。老实说，我不完全清楚为什么会这样，如果有人能附加一条评论，说明到底发生了什么，我将不胜感激
libxslt-dev
libxml2-dev
ruby-dev
