Nokogiri构建本地扩展宝石失败（RuntimeError）？

我正在尝试使用以下命令安装Nokogiri：

sudo gem install nokogiri

这是安装后遇到的混乱：

ERROR:  Error installing nokogiri:

我希望能得到一些提示或建议。我正在使用Ruby 1.9.4和Rails 3.2.13，但是我无法弄清楚为什么它不起作用。我正在使用Mavericks，我认为这可能是问题所在。

我已经更新了Xcode等工具。

你是从XCode组件还是命令行安装了XCode命令行工具？ - Peter Goldstein

正如@PeterGoldstein所说，检查命令行工具是否已安装。转到首选项|下载，并在组件下确保选择了命令行工具。另外，我认为您不需要sudo。 - rainkinz

请检查mkmf.log文件以获取更多详细信息。那么你的mkmf.log有什么说法？ - mu is too short

有大约13个mkmf.log文件。我应该寻找什么？此外，在XCode中，首选项/下载下，没有任何关于命令行工具的选项。 - m. sherman

我尝试运行常规的gem安装，但它回应“权限被拒绝”，然后我查看了nokogiri文档，上面写着要输入“sudo gem install nokogiri”。 - m. sherman

这不是一个直接的解决方案，但是可以指导你朝正确的方向前进。 rvm 在解决自身问题方面非常可靠。按照以下步骤帮助 rvm 发挥其魔力：

运行 rvm requirements 查找缺失的内容。

使用 rvm pkg（在旧版的 rvm 上）或 rvm autolibs 安装缺失的软件包。

确保你在此过程中阅读了 rvm 要求你阅读的所有文档。

成功完成后，尝试安装 nokogiri。
