在OS X上通过RVM安装Ruby时运行'make'时出错Mountain Lion

Question

这是我第一次使用Ruby。我意识到不要使用sudo来安装Gems，所以我遵循这个tutotrial（http://pragmaticstudio.com/blog/2010/9/23/install-rails-ruby-mac）来安装RVM，以便我可以更新我的Ruby版本，然后安装Middleman（http://middlemanapp.com/）。

RVM安装工作，但在“#compiling”阶段，我得到以下错误安装Ruby 1.9.3时：

Error running 'make', please read /Users/Mark/.rvm/log/ruby-1.9.3-p385/make.log There has been an error while running make. Halting the installation.

我打开日志文件，不像很多的我已经等问题可以看到，该文件不包含对'readline'的引用，而是对'编译'，我假定它涉及到Ruby安装的'#compiling'阶段。下面是输出到make.log里：

如果我执行“make --version”我得到以下输出：

我在努力寻找精确匹配的问题，所以如果任何人都能帮上忙，那会很棒。

干杯，

Answer 1

我跟着一些建议在这里和链接和其他职位谷歌搜索，但最终，通过自制软件更新GCC是什么终于拿到了Ruby的安装请编译，完整。

具体的链接我用于更新GCC：Installing Ruby on Mac OS X 10.8.2

所以感谢所有帮助，我不能肯定，如果它是所有的更新和清理，以及GCC或只是GCC的组合，但我正在运行。

Answer 2

虽然你没有看到它实际上是造成了Readline的错误。正如atmosx所说，我会删除默认的MAC OS X安装的ruby，并从一开始就遵循这个过程。

或之后这个https://rvm.io/packages/readline/帮助解决的ReadLine。也可对照看一下这个前面的问题：Error running make when installing Ruby 1.8.7-p302 via RVM on Mac OS 10.5.8

So complete steps are:

rvm pkg install readline 
rvm remove 1.8.7 
rvm cleanup all 
rvm install 1.8.7 -C –with-readline-dir=$rvm_path/usr
