【问题描述】：

我已经通过 enthought 7.2 包安装了 python 2.7，我一直在尝试安装 pyraf 包，但是每次我尝试安装它时都会得到以下信息：

copying lib/pyraf/wutil.py -> build/lib.macosx-10.5-x86_64-2.7/pyraf
running build_ext
building 'pyraf.sscanfmodule' extension
creating build/temp.macosx-10.5-x86_64-2.7

gcc: error: x86_64: No such file or directory
gcc: error: x86_64: No such file or directory
gcc: error: unrecognized option ‘-arch’
gcc: error: unrecognized option ‘-arch’
error: command 'gcc' failed with exit status 1

所以我认为这是一个架构问题，所以我重新安装了软件包（i386，XCode）然后得到了这个

running install
running build
running build_py
copying lib/pyraf/svn_version.py -> build/lib.macosx-10.5-i386-2.7/pyraf

gcc: error: i386: No such file or directory
gcc: error: i386: No such file or directory
gcc: error: unrecognized option ‘-arch’
gcc: error: unrecognized option ‘-arch’

后来在我看来真正的问题是 gcc 版本问题，所以我寻找任何安装的 gcc，我发现了这个：

所以我决定在我的 .bash_profile 文件中使用别名行指出正确的 gcc 版本，它根本不起作用。

我尝试设置 gcc 环境并构建 pyraf setup.py 并得到了这个：

Giotto:pyraf-dev Huguito$ export CC=/usr/bin/gcc-4.2

Giotto:pyraf-dev Huguito$ python setup.py build


running build
running build_py
copying lib/pyraf/svn_version.py -> build/lib.macosx-10.5-i386-2.7/pyraf
running build_ext

/Developer/SDKs/MacOSX10.5.sdk -DNDEBUG -g -O3 -arch i386 -isysroot     
/Developer/SDKs/MacOSX10.5.sdk -
I/Library/Frameworks/Python.framework/Versions/7.2/include/python2.7 -
I/usr/X11R6/include -
I/Library/Frameworks/Python.framework/Versions/7.2/include/python2.7 -c 
src/sscanfmodule.c -o build/temp.macosx-10.5-i386-2.7/src/sscanfmodule.o
gcc -bundle -undefined dynamic_lookup -g -arch i386 build/temp.macosx-10.5-i386-
2.7/src/sscanfmodule.o -o build/lib.macosx-10.5-i386-2.7/pyraf/sscanfmodule.so
gcc: error: i386: No such file or directory
gcc: error: unrecognized option ‘-arch’
error: command 'gcc' failed with exit status 1

如果我键入 gcc 命令但没有 -arch i386 标志：

Giotto:pyraf-dev Huguito$ gcc -fno-strict-aliasing -fno-common -dynamic -isysroot 
/Developer/SDKs/MacOSX10.5.sdk -DNDEBUG -g -O3 -isysroot /Developer/SDKs/MacOSX10.5.sdk 
-I/Library/Frameworks/Python.framework/Versions/7.2/include/python2.7 -
I/usr/X11R6/include -
I/Library/Frameworks/Python.framework/Versions/7.2/include/python2.7 -c 
src/sscanfmodule.c -o build/temp.macosx-10.5-i386-2.7/src/sscanfmodule.o

它似乎编译得很好，但是在重新编译后它会忽略它并且根本不起作用。

【参考方案1】：

试试看。 从 Xcode 安装命令行工具。在 Xcode -> 首选项 -> 下载 -> 组件 -> 命令行工具
