Lors de l'exécution pip install -r requirements.txt
, j'obtiens l'erreur suivante au cours de l'étape d'installation matplotlib
:
REQUIRED DEPENDENCIES AND EXTENSIONS
numpy: yes [not found. pip may install it below.]
dateutil: yes [dateutil was not found. It is required for date
axis support. pip/easy_install may attempt to
install it after matplotlib.]
tornado: yes [tornado was not found. It is required for the
WebAgg backend. pip/easy_install may attempt to
install it after matplotlib.]
pyparsing: yes [pyparsing was not found. It is required for
mathtext support. pip/easy_install may attempt to

be found. Using local copy.]

...
The following required packages can not be built:
* freetype
Ne devrait-il pas pip install -r requirements.txt
également installer freetype? Comment freetype doit-il être installé dans Ubuntu 12.04 pour qu'il fonctionne avec matplotlib
?
freetype2
ces jours-ci. Actualisé.
