捆绑安装在Nokogiri停止了
我试图在我的Rails应用程序上进行捆绑安装，并且它被困在“安装nokogiri”。 错误消息底部的说明说
Make sure that `gem install nokogiri -v '1.5.5'` succeeds before bundling. 有一次我看到了，我试过了
gem install nokogiri -v '1.5.5'
它告诉我安装Nokogiri时出错。 我在Mac上使用Ruby 1.9.2，在Rails 3.0.4应用程序中。
有人可以建议修复吗？

brew doctor说没有问题。 brew update说一切都已更新。 当我做brew install libxslt libxml2 libiconv我收到此错误：
Error: No available formula for libiconv Apple distributes libiconv with OS X, you can find it in /usr/lib. Some build scripts fail to detect it correctly, please check existing formulae for solutions.
当我尝试做gem install nokogiri我收到此错误：

假设您尚未安装Homebrew：
ruby -e "$(curl -fsSkL raw.github.com/mxcl/homebrew/go)" brew doctor
确保一切正常
brew update
为了能够安装libiconv
brew tap homebrew/dupes brew install libxslt libxml2 libiconv brew link libxslt libxml2 libiconv gem install nokogiri
如果您使用的是Ubuntu，请尝试：
sudo apt-get install libxslt-dev libxml2-dev gem install nokogiri
如果你使用的是Mac OS，可以尝试“ 为什么在Mac OS上安装Nokogiri会因为缺少libiconv而失败？ ”。
