pycurl instalados pero no encontraron

He estado tratando de instalar pycurl en un virtualenv con easy_install, y parece que se instala correctamente:pycurl instalados pero no encontraron

Adding pycurl 7.19.0 to easy-install.pth file

Processing dependencies for pycurl 
Finished processing dependencies for pycurl

Sin embargo, cuando se trata de usar, me sale el siguiente error:

Traceback (most recent call last):

ImportError: No module named pycurl

A pesar de que puedo ver claramente un pycurl-7.19.0-py2.7-linux-x86_64.egg en mi directorio ~/.virtualenvs/xxx/lib/python2.7/site-packages.

¡Cualquier sugerencia sobre cómo resolver este problema sería muy apreciada!

La distribución es Amazon Linux (EC2, 64 bit), Python es 2.7, instalado desde la fuente. curl, libcurl y libcurl-dev son suministrados por los repositorios de Amazon yum y están en la versión 7.19.7-26.20.

No puedo instalar el paquete pycurl proporcionado por los repos de Amazon porque la versión distribuida de python es 2.6 y mi proyecto se ejecuta en 2.7.

No es un problema de ruta, el contenido de sys.path es el siguiente:

>>> import sys; sys.path

¿Qué obtienes de sys.path? –

Tomasso: sys añadido.salida de ruta a la pregunta principal ya que el cuadro de comentarios es demasiado corto. No es un problema de ruta. ¿Cualquier otra sugerencia? – majackson

he logrado (con un poco de ayuda) para resolver el problema. El problema es que después de la instalación, pycurl.so no se copia a los paquetes de sitio para este virtualenv.

Al instalar usando pip -v install pycurl, se da el siguiente resultado:

El error clave aquí es: gcc -pthread -shared build/temp.linux-x86_64-2.7/src/pycurl.o -L/opt/python2.7/lib -lcurl -lpython2.7 -o build/lib.linux-x86_64-2.7/pycurl.so unknown option: --static-libs Usage: curl-config [OPTION] Available values for OPTION include: --ca ca bundle install path --cc compiler --cflags pre-processor and compiler flags --checkfor [version] check for (lib)curl of the specified version --features newline separated list of enabled features --help display this help and exit --libs library linking information --prefix curl install prefix --protocols newline separated list of enabled protocols --version output version information --vernum output the version information as a number (hexadecimal)

lo que demuestra que curl-config está siendo llamado con el argumento --static-libs, que no logra reconocer y en su lugar imprime su salida de 'uso'. Lo más importante es que devuelve un resultado sin código de error que hace que el compilador asuma que la compilación pycurl.so fue exitosa.

Esto se describe en más detalle here

La solución a este problema fue modificar setup.py y cambio de línea 101 de la pycurl para leer --libs en lugar de --static-libs. Esto provoca que pycurl.so se genere y copie al directorio site-packages correctamente.

Esto me salvó el día. Me he estado volviendo loco intentando instalarlo en mi virtualenv. ¡Gracias! –

Actualización de 2015 sobre este tema.
Me encontré con esta instalación de Pycurl en una Mac con Yosemite. He cambiado la línea en setup.py como se muestra a continuación:

for option in ["--libs", "--static-libs"]:

for option in ["--libs"]:

Entonces corrieron:

$>python setup.py install

instalación funcionó a la perfección después de esto!
