见鬼了。这样执行以后出现下列错误。系统是 mac os x lion

➜  ~  gem install bundler rails

你倒不如完整贴出 console 里面的 log，从执行开始一直到结束。

gem install bundler rails

安装过程中会安装所有的依赖包，而有些 gem 包是带有 C 扩展的，而你遇到的可能是环境依赖问题或者是编译环境的问题，你安装的是 XCode 4.2.1 么？给出你的 gcc 版本信息

gcc -v

新版本的 XCode 4.2.1 移除了 gcc , 默认使用 llvm，这个有可能是问题的根源，为了兼容性考虑，现阶段最佳方案是安装 XCode 4.1 而不是最新版本。

#2 楼 @KennX 那到不必，最近我重新装过一遍 Lion，也是被这个问题折腾了好久，很可能是用 XCode 编译出来的 ruby-1.9.2-p290 的问题，目前也没有完全搞定，我已经下载好了 XCode 4.1，逼急了我就把 XCode 的版本降级回去。你可以按照这篇文章里面的方案先试试看： http://rors.org/2011/10/25/compiling-ruby-on-a-fresh-lion-install.html

#3 楼 @lgn21st 

➜  ~  xcodebuild -version
Xcode 4.1
Build version 4B110

i 搞定了。。已经在安装了。

我之前也有这个类似的 GCC 版本问题，不过这个有怪了，目前我这台上面 GCC 就是这个版本

#5 楼 @huacnlee 我本身是 4.1。。上次更新的时候，我也更新了。我还以为自己是 4.2.1。结果多亏 itunes 的网速。没让我成功。

出现这个问题确实很奇怪，rvm remove ruby-1.9.2 以后重新安装一次就好了。

还有就是看版本像是 ruby 是 64 位的。会有影响不？

#5 楼 @huacnlee 的确有这个问题

  Notes for Darwin ( Mac OS X )
    For Snow Leopard: Xcode Version 3.2.1 (1613) or later, such as 3.2.6 or Xcode 4.1.
    [ Please note that Xcode 3.x will *not* work on OS X Lion. The 'cross-over' is Xcode 4.1. ]

    You should download the Xcode tools from developer.apple.com, since the Snow Leopard dvd install contained bugs.
    You can find Xcode 4.1 for OS X Lion at:
    https://developer.apple.com/downloads/download.action?path=Developer_Tools/xcode_4.1_for_lion/xcode_4.1_for_lion.dmg

    ** Lion Users: Xcode Version 4.2.x for OS X Lion works only for ruby 1.9.3-p0 (or higher).
       It currently fails to build several other rubies and gems, as well as several Homebrew and
       Macports packages. Xcode Version 4.1 (4B110) works.
    ** NOTE: Currently, Node.js is having issues building with osx-gcc-installer. This is _not_ an RVM issue. This is
       because Node.js depends on the Carbon headers. ox-gcc-installer does not install these to the system.
       This issue only affects users using osx-gcc-installer, and not Xcode. The only fix is to install Xcode over osx-gcc-installer.

    For MacRuby: Install LLVM first.
    For JRuby:  Install the JDK. See http://developer.apple.com/java/download/  # Current Java version 1.6.0_26
    For IronRuby: Install Mono >= 2.6
    For Ruby 1.9.3: Install libksba # If using Homebrew, 'brew install libksba'

    To use an RVM installed Ruby as default, instead of the system ruby:
      rvm install 1.8.7 # installs patch 352: closest supported version
      rvm system ; rvm gemset export system.gems ; rvm 1.8.7 ; rvm gemset import system.gems # migrate your gems
      rvm --default 1.8.7

刚刚测试了一下 Lion + Xcode 4.2 安装 1.9.2-p290 跟 1.9.3-p0 的时候，只要加上--with-gcc=clang 就可以了。Clang(http://en.wikipedia.org/wiki/Clang) 就是个 LLVM 版的 GCC

lgn21st #9 November 23, 2011

#8 楼 @southwolf 的确，我目前用的 ruby 1.9.2 就是用这个方法才装上的，为此我还花了点时间研究了一些 C 编译环境，这里有一张图片，解释 GCC，LLVM 和 Clang 我认为最为清楚。

cyfdecyf #10 December 03, 2011

安装了 Xcode 4.2 以后 /usr/bin/gcc 其实是 llvm-gcc-4.2 的软链接，编译 Ruby 1.9 可能会有问题。

不需要降级 Xcode，rvm install 之前设置 CC 和 CXX 环境变量来指定使用 gcc 即可

export CC=/usr/bin/gcc-4.2
export CXX=/usr/bin/g++-4.2
cyfdecyf #11 December 03, 2011

#9 楼 @lgn21st 最新的 LLVM 3.0 放弃 llvm-gcc 了

http://llvm.org/docs/ReleaseNotes.html#whatsnew

llvm-gcc is no longer supported, and not included in the release. We recommend switching to Clang or DragonEgg.

shenxiaochun #12 February 03, 2012

我升级了 Xcode 也遇到这个问题 rvm install 1.9.3 --with-gcc=clang

Xcode 中编译器版本的原因 参考 http://stackoverflow.com/questions/8032824/cant-install-ruby-under-lion-with-rvm-gcc-issues

xmsai #13 May 09, 2012

rvm install 1.9.3 --with-gcc=clang 报错 看来只能装 xcode4.1 了
