问题描述
我在安装jekyll时遇到了一些麻烦。无法完全弄清楚如何修补缺失的链接。我认为这是对Ruby的更新，但RVM在安装替代版本的ruby时也遇到了问题。
继承人全文：
$ sudo gem install jekyll
错误：安装jekyll时出错：
错误：无法构建gem本机扩展。
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb
mkmf.rb无法找到ruby的头文件在/ System / Library / Frameworks / Ruby.framework / Versions / 1.8 / usr / lib / ruby / ruby.h
Gem文件将保留安装在/Library/Ruby/Gems/1.8/gems/ fast-stemmer-1.0.1进行检查。
结果记录到/Library/Ruby/Gems/1.8/gems/fast-stemmer-1.0.1/ext/gem_make.out
这是否意味着我需要通过rvm更新我使用的ruby版本？
你的问题是，你的系统不知道make的位置在哪里，或者你没有安装它。解决这个问题的最简单方法就是安装xcode，并且可能会遇到其他问题（试图让ruby系统启动并运行）。

I'm having some trouble installing jekyll. Can't quite figure out how to patch the missing link. I think it's an update to Ruby, but RVM is having trouble installing alternate versions of ruby as well.
Heres the full post:
$ sudo gem install jekyll
ERROR: Error installing jekyll:
ERROR: Failed to build gem native extension.
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb
mkmf.rb can't find header files for ruby at /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/ruby.h
Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/fast-stemmer-1.0.1 for inspection.
Results logged to /Library/Ruby/Gems/1.8/gems/fast-stemmer-1.0.1/ext/gem_make.out
Does this mean I need to update the version of ruby I'm using via rvm?
Your problem is that either you system doesn't know where make is located at or you don't have it installed. The easiest way to fix this (and probably other issues you'll run into trying to get a ruby system up and running) is to install xcode.
You can get it at http://itunes.apple.com/us/app/xcode/id497799835?ls=1&mt=12 for lion. Or it came on a CD with your computer for earlier versions.
If you're using Lion, please see comments below for a link to how to install developer tools on Lion.
