Broken Pipe error when using pip to install pycrypto on Mac OS X

问题

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.

Here is the error that I am getting:

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).

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

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

回答1:

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 ...

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.

Xcode 5.1

ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future pip2.7 install pycrypto
