捆绑安装在 Nokogiri 停止答案

【问题标题】：bundle install stopped at Nokogiri捆绑安装在 Nokogiri 停止
【发布时间】：2012-12-16 01:50:03
【问题描述】：

我尝试在我的 Rails 应用程序上进行捆绑安装，但它卡在“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.

看到之后，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。

谁能提出解决办法？

An error occurred while installing nokogiri (1.5.5), and Bundler cannot continue.
Make sure that `gem install nokogiri -v '1.5.5'` succeeds before bundling.

brew doctor 表示没有问题。 brew update 说一切都已经更新了。当我执行brew install libxslt libxml2 libiconv 时，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.

当我尝试执行 gem install nokogiri 时，我收到此错误：

【解决方案1】：

假设你还没有安装 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

【讨论】：

我应该安装 Xcode 吗？已经安装了……你的意思是卸载吗？
我的 brew 更新失败，所以我无法尝试其余的答案。由于 brew update 问题是一个不同的问题，我为它提出了一个新问题。修复后，我将尝试您的其余解决方案stackoverflow.com/questions/14113427/brew-update-failed
无法让它工作。 brew doctor 和 brew update 说一切都很好，但是当我按照你的指示之后，它就不起作用了。我已经更新了 OP。

【解决方案2】：

如果您使用的是 Ubuntu，请尝试：

sudo apt-get install libxslt-dev libxml2-dev
gem install nokogiri

如果您使用的是 Mac OS，不妨试试“Why does installing Nokogiri on Mac OS fail with libiconv is missing?”。

【解决方案3】：

对我来说，问题已经解决了：

bundle lock --add-platform x86-mingw32 x86-mswin32 x64-mingw32 java

gem install nokogiri

Shows this message on "bundle update"
