在Mac OS X上使用pip安装pycrypto时出现Broken Pipe错误
我正在尝试通过pip在OS X上安装pycrypto（版本2.3）。但是，当编译器试图编译MD2.c时，我遇到了一个“Broken pipe”的错误。在使用easy_install时，我也遇到了非常类似的错误。
这是我遇到的错误信息：

我尝试使用mac ports来安装这个包，命令是“sudo port install py26-crypto”，看起来安装得很顺利，但在运行“fab”（Fabric）命令时，它告诉我pycrypto包缺失。
我还尝试了YH Wong在这里推荐的“ARCHFLAGS”命令，但没有成功：https://superuser.com/questions/259278/python-2-6-1-pycrypto-2-3-pypi-package-broken-pipe-during-build
我使用的是Mac OS X 10.6.7，Python版本是2.6.6，并且已经安装了XCode。

Xcode 5.1
ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future pip2.7 install pycrypto
65
如果你安装了Xcode 4，可以在使用 pip 或 easy_install 之前先设置一下 ARCHFLAGS：
sudo bash
export ARCHFLAGS='-arch i386 -arch x86_64'
pip ...
问题在于，Xcode 4 不再支持 -arch ppc 这个选项，而在 Mac OS X 10.6 上的系统自带 Python 2.6 需要用到这三种架构来构建通用的 C 扩展模块。如果你在使用 sudo 命令之前设置了这个环境变量，它可能不会被传递到 sudo 的环境中。
