Error de Broken Pipe al usar pip para instalar Pycrypto en Mac OS X

Question

Estoy intentando instalar Pycrypto (versión 2.3) en OS X a través de pip. Obtengo un error de "conexión interrumpida" cuando el compilador intenta compilar MD2.c. Aparece un error muy similar cuando uso easy_install.

Aquí está el error que estoy recibiendo:

Intenté instalar este paquete usando puertos mac con el comando "sudo port install py26-crypto", y parece que se instalará sin problemas, pero luego me dice que el paquete pycrypto falta al ejecutar el comando "fab" (Fabric).

Intenté usar el comando "ARCHFLAGS" recomendado en respuesta por YH Wong aquí, pero no tuve suerte: https://superuser.com/questions/259278/python-2-6-1-pycrypto-2-3-pypi-package-broken-pipe-during-build

Estoy usando Mac OS X 10.6.7 con Python 2.6.6 y XCode está instalado.

Answer 1

Si ha instalado Xcode 4, intente configurar ARCHFLAGS antes de llamar a pip o easy_install :

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

El problema es que Xcode 4 ha eliminado el soporte para -arch ppc pero el sistema Python 2.6 en Mac OS X 10.6 espera construir módulos de extensión universales C con las tres arquitecturas. Y si define la variable de entorno antes del comando sudo, probablemente no se exportará al entorno sudo.

Answer 2

Xcode 5.1

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