Make sure that `gem install nokogiri -v '1.6.1'` succeeds before bundling. 所以我试过了 gem install nokogiri -v '1.6.1' 这确实奏效了。当然这会让我很高兴，但我现在想知
bundle安装时An error occurred while installing nokogiri (1.6.1), and Bundler cannot continue.
Make sure that `gem install nokogiri -v '1.6.1'` succeeds before bundling.
gem install nokogiri -v '1.6.1'
bundle安装也成功了
我正在运行MacOSX10.9.2
这是我第一次运行捆绑安装时的日志

试试这个：
brew install libxml2 libxslt libiconv
无法仅通过bundle install
安装它的原因是bundler
只处理gem依赖项，而不是本地依赖项。gem要求您的系统具有您没有的libxml2
。所以你需要安装它们。提示我答案的是日志中的以下错误消息：
ERROR: Failed to build gem native extension.
缺少依赖项时出错。你试过安装它们吗？谢谢你的提示。我的问题是为什么我可以通过gem install
安装gem，而不是通过bundle install
安装gem。但是gem install nokogiri-v'1.6.1'
安装所需的依赖项吗？不太确定。。原因可能是--include dependencies
是gem install
的默认选项，您的假设可能是正确的。由于它现在已成功安装，因此很难找出实际问题所在。
