extconf 失败，在 OS X Yosemite 10.10.5 上安装 [Ruby on Rails] 5 时退出代码 1 错误

Question

我正在尝试按照 rails 站点上的说明在 OS X Yosemite 10.10.5 上安装 Ruby on Rails v5：

http://railsapps.github.io/installrubyonrails-mac.html

当我运行这个：

sudo gem install rails --version 5.0.0 --no-ri --no-rdoc

我收到错误ERROR: Failed to build gem native extension。以下是我的命令行上可能有用的部分输出：

current directory: /Users/me/.rvm/rubies/ruby-2.3.0/lib/ruby/gems/2.3.0/gems/nokogiri-1.6.8/ext/nokogiri

    To see why this extension failed to compile, please check the mkmf.log which can be found here:

这是 mkmf.log 文件的一部分：

我不知道发生了什么:(。有人可以帮忙吗？

红宝石版本：2.3.0p0。红宝石版本：2.5.1

xcode-select 安装成功。

谢谢！

Answer 1

http://www.nokogiri.org/tutorials/installing_nokogiri.html说他们建议使用包含的库进行安装，而不是使用系统库进行安装。

所以我尝试（在 Ubuntu 上）按照那里的说明进行操作，它奏效了

sudo apt-get install build-essential patch ruby-dev zlib1g-dev liblzma-dev
gem install nokogiri

Answer 2

我解决了。该错误与 nokogiri 有关。我是单独安装的，参数-- --use-system-libraries：

gem install nokogiri -- --use-system-libraries

后来我成功地安装了导轨，没有出现错误。
