我刚刚升级到OS X Mountain Lion(已经后悔) .
安装json gem的本机扩展时遇到问题 .
10.8之前我安装了命令行工具 . RVM与Ruby 1.9.2 .
升级到10.8并做了以下事情:
-
sudo chown -R
whoami
/ usr / local -
brew更新
-
brew tap homebrew / dupes
-
brew安装apple-gcc42
-
安装了XCode 4.4
-
已安装的XCode 4.4命令行工具
在bash_profile中 -
export CC = / usr / local / bin / gcc-4.2
-
sudo ln -s /usr/local/bin/gcc-4.2 /usr/bin/gcc-4.2
-
编辑:sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer
安装json gem时,我仍然得到以下输出:
➽ gem install json -v '1.7.4'
Building native extensions. This could take a while...
ERROR: Error installing json:

这里有什么帮助?如何调试我的构建环境?在这方面不是专家,但我认为json gem安装程序忽略了我的环境,因为它使用的是我的系统上不存在的GCC版本,而brew安装程序也没有创建它 .
➽ gcc-4.2
i686-apple-darwin11-gcc-4.2.1: no input files
➽ which gcc-4.2
/usr/local/bin/gcc-4.2
➽ ls /usr/bin/i686-apple-darwin11-gcc-4.2.1
ls: /usr/bin/i686-apple-darwin11-gcc-4.2.1: No such file or directory
我也试过symlinking ➽ sudo link /usr/local/bin/gcc-4.2 /usr/bin/i686-apple-darwin11-gcc-4.2.1
. 但是这给了一个vfork超时错误 .
编辑:
➽ brew doctor
gcc-4.2: error trying to exec '/usr/bin/i686-apple-darwin11-gcc-4.2.1': execvp: No such file or directory
Warning: X11 is not installed.
You don't have X11 installed as part of your OS X installation.
This is not required for all formulae, but is expected by some.
You can download the latest version of XQuartz from:
https://xquartz.macosforge.org
EDIT2:
确实运行了xcode-select XCode
EDIT3:
sudo xcode-select -switch /usr/bin
sudo ln -sf /usr/bin/llvm-gcc-4.2 /usr/bin/gcc-4.2
这固定了!基本上你告诉OS X使用/ usr / bin文件夹进行编译,然后将llvm-gcc-4.2编译器链接到以前的编译器 . 作品! BAM!

我的印象是你需要做的就是:
我尝试使用xcode-select XCode和命令行工具 . 他们都工作 . 我还卸载了brew apple-gcc42,它仍然有效 . 也不需要导出CC .
所以基本上只是链接 . 希望这能解决人们遇到的一些问题 .
你运行:
让你的系统使用Xcode提供的命令行工具?
在这个SO answer中多一点 .
更简单的方法..我只是通过编辑rbconfig.rb文件来修复根问题〜/ .rvm / rubies / ruby-1.9.3-p327 / lib / ruby / 1.9.1 / x86_64-darwin12.2.0
由于某种原因,文件被设置为使用gcc-4.2用于CC而不仅仅是计划gcc(IS llvm-gcc-4.2) .
