Problèmes avec pip install numpy - RuntimeError : Broken toolchain : impossible de lier un simple programme C

Question

J'essaie d'installer numpy (et scipy et matplotlib) dans un virturalenv.

Mais je continue à avoir ces erreurs :

RuntimeError: Broken toolchain: cannot link a simple C program

----------------------------------------
Cleaning up...
Command python setup.py egg_info failed with error code 1

J'ai installé les outils de ligne de commande pour xcode.

$ which gcc
/usr/bin/gcc
$ which cc
/usr/bin/cc

Je suis sur Mac OSX 10.9 J'utilise un python installé par brew

Editar
Oui, j'essaie d'installer avec pip.
L'ensemble de la traceback est énorme (>400 lignes)

RuntimeError: Broken toolchain: cannot link a simple C program

Answer 1

Cela signifie qu'il ne peut pas trouver votre compilateur C. Essayez d'installer le compilateur gcc si la liaison avec un autre compilateur échoue.

Answer 2

Ce qui précède n'a fonctionné pour moi qu'après avoir installé python3-dev.

Answer 3

J'ai résolu ce problème en utilisant Conda au lieu de pip dans mon Dockerfile : FROM continuumio/miniconda3:latest

Answer 4

Vieux sujet, mais mon problème était que je n'avais pas installé Xcode. Ce qui suit l'a résolu.

xcode-select --install
