在OS X Lion上安装PIL(完整的菜鸟)

Question

我想运行python的ndimage来做一些图像分析.我有一台运行OSX Lion和Python 2.7的64位Mac.当我尝试从ndimage命令运行命令时,我发现我需要安装PIL.

我下载并解压缩它(现在进入下载文件夹,有没有更好的地方去做？).我运行setup.py并获取以下消息:

running install
running build
running build_py
running build_ext
--- using frameworks at /System/Library/Frameworks
building '_imaging' extension
gcc-4.2 -fno-strict-aliasing -fno-common -dynamic -isysroot /Developer/SDKs/MacOSX10.6.sdk -arch i386 -arch x86_64 -g -O2 -DNDEBUG -g -O3 -DHAVE_LIBZ -I/System/Library/Frameworks/Tcl.framework/Headers -I/System/Library/Frameworks/Tk.framework/Headers -IlibImaging -I/Library/Frameworks/Python.framework/Versions/2.7/include -I/usr/include -I/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7 -c _imaging.c -o build/temp.macosx-10.6-intel-2.7/_imaging.o
unable to execute gcc-4.2: No such file or directory
error: command 'gcc-4.2' failed with exit status 1

我读到无法在Mac OS X 10.7 Lion上构建PIL并确保我安装了32/64位版本的python 2.7(Mac OS X 64位/ 32位x86-64/i386安装程序(2.7.2)对于Mac OS X 10.6和10.7).我也安装了Xcode.我在这里做些蠢事吗？

编辑1: 进一步看,我发现这个gcc-4.2失败,退出状态为1.我收到错误后尝试输入此内容:

llvm-gcc-4.2 -fno-strict-aliasing -fno-common -dynamic -isysroot /Developer/SDKs/MacOSX10.6.sdk -arch i386 -arch x86_64 -g -O2 -DNDEBUG -g -O3 -DHAVE_LIBZ -I/System/Library/Frameworks/Tcl.framework/Headers -I/System/Library/Frameworks/Tk.framework/Headers -IlibImaging -I/Library/Frameworks/Python.framework/Versions/2.7/include -I/usr/include -I/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7 -c _imaging.c -o build/temp.macosx-10.6-intel-2.7/_imaging.o

我收到这些消息:

_imaging.c:3017: warning: initialization from incompatible pointer type
_imaging.c:3077: warning: initialization from incompatible pointer type
_imaging.c:3017: warning: initialization from incompatible pointer type
_imaging.c:3077: warning: initialization from incompatible pointer type

编辑2: 我不确定这是否是正确的方法,但我发现了一篇关于在OSX Leopard上安装pil的帖子,并根据其建议,删除-arch i386了命令的一部分并输入:

 llvm-gcc-4.2 -fno-strict-aliasing -fno-common -dynamic -isysroot /Developer/SDKs/MacOSX10.6.sdk -arch x86_64 -g -O2 -DNDEBUG -g -O3 -DHAVE_LIBZ -I/System/Library/Frameworks/Tcl.framework/Headers -I/System/Library/Frameworks/Tk.framework/Headers -IlibImaging -I/Library/Frameworks/Python.framework/Versions/2.7/include -I/usr/include -I/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7 -c _imaging.c -o build/temp.macosx-10.6-intel-2.7/_imaging.o

现在我只收到两个错误:

_imaging.c:3017: warning: initialization from incompatible pointer type
_imaging.c:3077: warning: initialization from incompatible pointer type

从我在这一点上可以看出,程序已经消失并且没有完成编译.谁能帮助我从这里拿走它？

下载 Lion 的 GCC。它解决了所有错误：command 'gcc-4.2' failed with exit status 1 issues。
