安装Nokogiri gem出现错误

ruby-on-railsruby
3

我在Mac OS 10.9.2上安装nokogiri gem时遇到了问题。我尝试使用brew install libxml来解决任何依赖关系，但似乎没有起作用。我不确定如何解决它与clang产生的链接问题。

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

这是唯一对我有效的命令：
sudo ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future gem install nokogiri

我一直在使用Yosemite遇到了“libxml2缺失”的问题，尝试了各种方法都没有解决。设置xml2-lib作为参数等等，都没有起作用。直到我添加了ARCHFLAGS命令才解决了问题。非常感谢！ - undefined

我首先使用brew install libxml2 libxslt来解决问题。然后，我需要从这里下载晚于10月末的旧版本xcode-select开发工具https://developer.apple.com/downloads/index.action#。

之后，运行sudo gem install nokogiri最终成功了。

在将OS X从Mountain Lion升级到Maverick后，安装nokogiri时遇到错误。通过重新安装命令行工具解决了该错误。

  • brew doctor
  • xcode-select --install

我的环境：Ruby 2.1，rvm，Rails 4.1.1

这对我在一个搭载了10.9.3系统的系统上解决了问题。这适用于不仅仅是升级。谢谢！ - undefined

你可以进入位于 $HOME/.bundler/tmp/63074/gems/nokogiri-1.6.1 的 Makefile 并编辑开关以作为临时解决方案。就我而言，它在我的系统上成功了。

这些开关在哪里可以找到？ - undefined
我从github上检出了源代码，并在nokogiri/ext/nokogiri/extconf.rb中找到了相关文件。我不确定为什么你的构建失败了，因为我的在OS X上使用ruby-2.0.0-p451顺利成功了。 - undefined
你在那个文件中指的是哪些行号？ - undefined
为什么不将nokogiri/ext/nokogiri/extconf.rb的内容更新到你的问题中，这样更容易帮助你呀？ - undefined
我已经为您添加了它。 - undefined
