【问题描述】：
我正在尝试使用最新版本的 Ruby 安装带有 RVM 的 Rails，但在安装 Nokogiri 时遇到了问题。
我已经有一些使用 Ruby 2.4.0 的 RVM gemset，我没有遇到任何问题。我安装了 Ruby 2.4.1：
rvm install ruby-2.4.0
并创建了一个新的 gemset：
rvm use ruby-2.4.1@quiniela --create
然后跑：
gem install rails --pre
我得到了这个错误：
ERROR: Error installing rails:
ERROR: Failed to build gem native extension.

To see why this extension failed to compile, please check the mkmf.log which can be found here:
/Users/andres/.rvm/gems/ruby-2.4.1@quiniela/extensions/x86_64-darwin-16/2.4.0/nokogiri-1.7.1/mkmf.log
extconf failed, exit code 1
看来是Nokogiri的问题。
我按照“Error installing nokogiri: Failed to build gem native extension & libiconv is missing (OSX)”中的建议没有成功。
我更新了 RVM 并运行了 gem update，但它没有用。 Xcode 也更新了。
有人遇到过这个问题吗？

您无法使用
rvm install ruby-2.4.0安装 Ruby 2.4.1。 /Users/andres/.rvm/gems/ruby-2.4.1@quiniela/extensions/x86_64-darwin-16/2.4.0/nokogiri-1.7.1/mkmf.log 说问题是什么？当你更新 Xcode 时你做了什么？您是否重新安装了命令行选项？
