Question

我正在使用Mac OS X Mountain Lion（10.8.3）。

我正在关注railstutorial.org教程。在第3章中，它们在gemfile中包含"gem 'rspec-rails', '2.11.0'"。从那时起，我无法让bundle update在我的应用程序中工作，因为它正在尝试安装Nokogiri，这不起作用，但我不明白为什么。

这是我运行bundle update时在控制台中发生的事情：

在应用程序目录中运行bundle在控制台中获取相同的消息：

"An error occurred while installing nokogiri (1.5.9), and Bundler cannot
continue.
Make sure that `gem install nokogiri -v '1.5.9'` succeeds before bundling."

我尝试gem install nokogiri，在控制台中输出：

Answer 1

尝试只运行bundle。可能存在由bundle update引起的依赖性问题。

同时尝试gem install nokogiri，并报告其输出。

好的，gem install输出很有帮助。据我所知，您使用的是MacPorts，其中包括：

与家庭酿造相比，完全打击。
用户升级操作系统时会出现一些迁移问题。

我会尝试安装自制程序，或重新安装MacPorts。

另外，从我所知的错误消息来看，主要问题归结为软件不兼容，无论是32位软件还是64位机器，反之亦然。也许你不小心下载了错误的版本。

Answer 2

通过Homebrew和RVM进行全新安装似乎解决了这个问题。捆绑更新无误，nokogiri错误消失。

我使用RailsInstaller安装Ruby + Rails，之前用Rails Installer重新安装两次，同样的问题。使用自制软件后，问题消失了RVM。

使用 X代码4.6， RVM，自制， Ruby 1.9.3p374， Rails 3.2.13

Bundler不会因为nokogiri而更新，已经安装了libxml2，有什么问题？
