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“Broken pipeline”错误。使用 easy_install 时我遇到了非常类似的错误。
这是我收到的错误：

我尝试使用 mac ports 和命令“sudo port install py26-crypto”来安装这个包，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 在这里回答中推荐的“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 https://superuser.com/questions/259278/python-2-6-1-pycrypto-2-3-pypi-package-broken-pipe-during-build
我使用 Mac OS X 10.6.7 和 python 2.6.6 并安装了 XCode。
如果您已经安装了 Xcode 4，请尝试设置ARCHFLAGS打电话之前pip or easy_install:
sudo bash
export ARCHFLAGS='-arch i386 -arch x86_64'
pip ...
问题是 Xcode 4 已经删除了对-arch ppc但 Mac OS X 10.6 上的系统 Python 2.6 期望构建具有所有三种架构的通用 C 扩展模块。如果您在 sudo 命令之前定义环境变量，则它可能不会导出到 sudo 环境。
