一段时间前，我做了一个简单的bundle update，让我所有的宝石在我的Ruby on Rails项目上更新。然而，有一次，我得到了一个关于Nokogiri的错误:
Building nokogiri using packaged libraries.
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.
/Users/scott/.rvm/rubies/ruby-2.1.1/bin/ruby extconf.rb
Building nokogiri using packaged libraries.
-----
libiconv is missing. please visit http://nokogiri.org/tutorials/installing_nokogiri.html for help with installing dependencies.
-----
我做了一些狩猎，并在Nokogiri网站上找到了处理这个问题的说明。根据说明手动安装libiconv后，如下工作:
gem update nokogiri -- --with-iconv-include=/usr/local/Cellar/libiconv/1.13.1/include --with-iconv-lib=/usr/local/Cellar/libiconv/1.13.1/lib
所以之后我可以运行bundle update，一切都很好!令人讨厌的是，每次我运行bundle update时，我都要经历这个过程，因为Nokogiri更新得比较频繁……有没有一种自动处理的方法?我知道野尻是一颗受欢迎的宝石!很多人都遇到过这个问题。
更新:按照@Tim Moore的要求，我的bundle env命令的输出:
scotts-mbp:ucode scott$ bundle env
