Une des deux erreurs est corrigée, le dépôt de win32-x64-83_binding.node est réparé.
Euh, correctif : je ne sais plus où j'ai vu ça, on voit bien toujours une erreur 404. Peut-être que j'ai vu "downloading ..." et que ça me prenait tellement le chou que je me suis enthousiasmé tout de suite, trop vite.

Il reste l'autre erreur,

Code:

gyp ERR! stack import sys; print "%s.%s.%s" % sys.version_info[:3];

Il semble que ceci soit une syntaxe de Python 2. Voir au-dessus la ligne 50 :

Code:

gyp verb `which` failed Error: not found: python2

or en ligne je ne trouve plus que Python 3.

https://mail.python.org/archives/lis...BGQIZHAVRHCV2/

Donc il faut soit trouver Python 2 et l'installer, soit corriger node-sass pour qu'il fasse appel à Python 3. La seconde possibilité semble plus rationnelle, mais pour ça je ne peux que prendre mon mal en patience, pas vrai ?
Pratique, ça, quand on est en équilibre sur une patte à attendre pour envoyer sa candidature ...
