ruby - 捆绑安装在 Nokogiri 停止

Question

我试图在我的 Rails 应用程序上进行捆绑安装，但它卡在了“正在安装 nokogiri”处。错误消息底部的说明说

Make sure that `gem install nokogiri -v '1.5.5'` succeeds before bundling.

当我看到它时，我尝试了

gem install nokogiri -v '1.5.5'

它告诉我安装 Nokogiri 时出错。我在 Mac 上的 Rails 3.0.4 应用程序中使用 Ruby 1.9.2。

任何人都可以提出修复建议吗？

brew doctor 说没有问题。 brew update 表示所有内容都已更新。当我执行 brew install libxslt libxml2 libiconv 时，出现此错误:

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.

当我尝试执行 gem install nokogiri 时出现此错误:

假设您还没有安装 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
