Ruby 2.1和Nokogiri安裝錯誤？

我知道這是一個在這裏多次「解決」的問題，但我嘗試了所有的解決方案，仍然無法實現。這是我的錯誤：Ruby 2.1和Nokogiri安裝錯誤？

當我已經通過BREW安裝的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

我曾嘗試一切在這個和其他線程：「Install Nokogiri 1.6.1 under Ruby 2.0.0p353 (rvm based installation) fails (OSX Mavericks)?」

另外我甚至沒有在我的Gemfile中定義Nokogiri。

OK，我發現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

    5 checking for a thread-safe mkdir -p... ./install-sh -c -d 
    6 checking for gawk... no 
    7 checking for mawk... no

    9 checking for awk... awk 
10 checking whether make sets $(MAKE)... yes 
11 checking for gcc... gcc-4.2.1 
12 checking whether the C compiler works... no 
13 configure: error: in `/Users/josh/.rvm/gems/ruby-2.1.0/gems/nokogiri-1.6.1/ext/nokogiri/tmp/ports/libxml2/2.8.0/libxml2-2.8.0': 
14 configure: error: C compiler cannot create executables 
15 See `config.log' for more details

而在我的config.log發現：

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

又是什麼告訴你？ –

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

不確定是否有問題，但是你運行Mac OS Maverick？你有沒有更新Xcode？打開並接受新的規則？並再試一次... –

原來我不是引用的C編譯正常。在我的「的.bash_profile」我有：

export CC=gcc-4.2.1

，我和取代它：‘檢查mkmf.log文件的更多細節’

export CC=gcc

所以現在* nokogiri *正在編譯？ –

是的，這允許它正確編譯 – jwilcox09

接受你的答案=） –
