python - Todavía no se puede instalar scipy debido a la falta de compilador fortran después de preparar gcc en Mac OS X



macos numpy (3)

Depende de la versión gcc. Verifica tu versión de gcc:

Depends: gcc-4.8-base (= 4.8.2-19ubuntu1) but 4.8.4-2ubuntu1~14.04 is to be installed

Actualice su versión de gcc: http://ubuntuhandbook.org/index.php/2013/08/install-gcc-4-8-via-ppa-in-ubuntu-12-04-13-04/

He leído y seguido esta respuesta para instalar scipy / numpy / theano. Sin embargo, todavía falló en el mismo error de falta del compilador de Fortran después de instalar brew gcc. Mientras HomeBrew instaló el gcc-4.8, no instaló ningún comando gfortran o g95. Me imagino que gfortran puede ser solo una synonymy de gcc, luego creo un enlace simbólico

$ cd /usr/local/bin $ ln -s gcc-4.8 gfortran $ pip install scipy

Luego detecta el comando gfortran pero sigue sin quejarse del compilador de Fortran.

¿Que más deberia hacer?


Lo siguiente me funcionó:

sudo apt-get install gfortran

en mi sistema:

Ubuntu 15.10 (Linux 4.2.0-19-genérico # 23-Ubuntu x86_64 x86_64 x86_64 GNU / Linux)


Se corrigió actualizando pip, aunque recién instalé mi pip / virtualenv la primera vez en el mismo día.
