Ruby 2.1和Nokogiri安装错误？

我知道这是一个在这里多次“解决”的问题，但我尝试了所有的解决方案，仍然无法实现。这是我的错误：Ruby 2.1和Nokogiri安装错误？

当我已经通过BREW安装的libxml2：

和RVM：

22-01-14 17:57:56> rvm list 

rvm rubies 

=* ruby-2.1.0 [ x86_64 ] 

# => - current 
# =* - current && default 
# * - default

和GCC：

22-01-14 17:57:56> gcc --version 
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1 
Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn) 
Target: x86_64-apple-darwin13.0.2 
Thread model: posix

我曾尝试一切在这个和其他线程： “Install Nokogiri 1.6.1 under Ruby 2.0.0p353 (rvm based installation) fails (OSX Mavericks)?”

另外我甚至没有在我的Gemfile中定义Nokogiri。

OK，我发现configure.log文件：

1 checking build system type... i386-apple-darwin13.0.2 
    2 checking host system type... i386-apple-darwin13.0.2 
    3 checking for a BSD-compatible install... /usr/bin/install -c

10 checking whether make sets $(MAKE)... yes 
11 checking for gcc... gcc-4.2.1

14 configure: error: C compiler cannot create executables 
15 See `config.log' for more details

而在我的config.log发现：

84 configure:3335: gcc-4.2.1 --version >&5 
85 configure: line 3337: gcc-4.2.1: command not found

又是什么告诉你？ –

我无法在任何地方找到它。 sudo find/Users/josh/-name mkmf.log – jwilcox09

不确定是否有问题，但是你运行Mac OS Maverick？你有没有更新Xcode？打开并接受新的规则？并再试一次... –

原来我不是引用的C编译正常。在我的“的.bash_profile”我有：

export CC=gcc-4.2.1

，我和取代它：‘检查mkmf.log文件的更多细节’

export CC=gcc

所以现在* nokogiri *正在编译？ –

是的，这允许它正确编译 – jwilcox09

接受你的答案=） –
