Question

J'ai beaucoup de problèmes pour installer numpy sur Mac OS X 10.6. Lorsque je tente de l'installer à partir de la source, je reçois l'erreur suivante:

Je Xcode déjà installé depuis que j'ai gcc (version i686-apple-darwin10-gcc-4.2.1 (GCC) 4.2.1) il semble donc peu probable que ces fichiers d'en-tête n'existent pas. Une idée de ce qui pourrait arriver?

merci.

Answer 1

Il existe une version (même un peu périmée) de numpy déjà incluse sur Mac OS X 10.6 dans l'installation par défaut de Python 2.6. Cependant, si vous voulez une version plus récente de numpy ou si vous voulez numpy + scipy, alors je vous suggère de lire mes instructions d'installation: Python2.6+NumPy+SciPy+MatPlotLib on Mac OS X 10.6.

Modifier
Quant aux messages d'erreur que vous obtenez .... Notez qu'il dit « 10.4 »; numpy a le SDK Mac OS X 10.4 codé en dur dedans pour une raison quelconque, donc si vous n'avez pas installé le SDK 10.4 (qui est facultatif et n'est pas installé par défaut), alors vous obtiendrez ces erreurs. Si vous réinstallez Xcode et sélectionnez le SDK Mac OS X 10.4 pour qu'il soit installé, cela devrait résoudre les problèmes que vous rencontrez. Cela dit, je recommande fortement d'installer MacPython 2.6 de Python.org et la version binaire de numpy.

Answer 2

J'ai installé le python emballé EPD avec tous les paquets scientifiques sur OS X 10.6 à partir de ces deux pages: http://cse.ucdavis.edu/~chaos/courses/nlp/Software/PythonOSXInstall.htmlhttp://www.soton.ac.uk/~fangohr/computing/pythonsoft.html

Espérons qu'il est utile.
