我正在尝试通过pip在OS X上安装pycrypto（版本2.3）。 当编译器尝试编译MD2.c时，我收到"管道断开"错误。 使用easy_install时，我遇到了非常相似的错误。
这是我收到的错误：

我尝试使用带有命令"sudo port install py26-crypto"的 mac 端口安装此软件包，并且看起来安装顺利，但随后它告诉我在运行命令"fab"（Fabric）时缺少 pycrypto 包。
我尝试使用YH Wong在这里回答时推荐的"ARCHFLAGS"命令，但没有运气：https://superuser.com/questions/259278/python-2-6-1-pycrypto-2-3-pypi-package-broken-pipe-during-build
我正在使用带有python 2.6.6的Mac OS X 10.6.7，并安装了XCode。
如果您已安装 Xcode 4，请在调用 pip 或 easy_install 之前尝试设置ARCHFLAGS：
sudo bash
export ARCHFLAGS='-arch i386 -arch x86_64'
pip ...
问题在于 Xcode 4 已经删除了对 -arch ppc 的支持，但 Mac OS X 10.6 上的系统 Python 2.6 希望构建具有所有三种架构的通用 C 扩展模块。 如果在 sudo 命令之前定义环境变量，它可能不会导出到 sudo 环境。
Xcode 5.1
ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future pip2.7 install pycrypto
