使用pip在Mac OS X上安装pycrypto时发生断管错误

问题描述：

我试图通过pip在OS X上安装pycrypto（版本2.3）。编译器试图编译MD2.c时，出现Broken pipe错误。使用easy_install时出现非常类似的错误。

I am attempting to install pycrypto (version 2.3) on OS X via pip. I am getting a "Broken pipe" error when the compiler attempts to compile MD2.c. I get a very similar error when using easy_install.

以下是我收到的错误：

Here is the error that I am getting:

我试图用命令sudo port install py26-crypto使用mac端口安装此软件包，并看起来顺利安装，但它告诉我，运行命令fab（结构）时，pycrypto软件包丢失。

I attempted to install this package using mac ports with the command "sudo port install py26-crypto", and looks to install smoothly but then it tells me that the pycrypto package is missing when running the command "fab" (Fabric).

我试图使用ARCHFLAGS命令在回答中推荐由YH黄在这里，但没有运气：

I attempted using the "ARCHFLAGS" command recommended in answer by YH Wong here but no luck: 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，安装了python 2.6.6并安装了XCode。

I am using Mac OS X 10.6.7 with python 2.6.6 and XCode is installed.

答

如果您已经安装了Xcode 4，请在调用 pip 或 ARCHFLAGS c> easy_install ：

If you have installed Xcode 4, try setting ARCHFLAGS before calling pip or easy_install:

sudo bash
export ARCHFLAGS='-arch i386 -arch x86_64'
pip ...

问题在于Xcode 4已经取消了对 -arch ppc 但Mac OS X 10.6上的系统Python 2.6希望构建具有所有三种体系结构的通用C扩展模块。如果你在sudo命令之前定义了环境变量，它可能不会被导出到sudo环境。

The problem is that Xcode 4 has removed support for -arch ppc but the system Python 2.6 on Mac OS X 10.6 expects to build universal C extension modules with all three architectures. And if you define the environment variable prior to the sudo command, it will likely not be exported through to the sudo environment.
