Installation des binaires précompilés me donne:

C:\Users\daniel.bak>pip install "C:\Users\daniel.bak\Downloads\lxml-3.6.0-cp35-cp35m-win_amd64.whl" 
lxml-3.6.0-cp35-cp35m-win_amd64.whl is not a supported wheel on this platform. 

Answer 1

Vous pouvez télécharger les binaires précompilés et les installer avec pip install

Voici le download link. cp27, cp34, cp35 indiquent des versions de Python et win32 et win_amd64 32 et paquets de 64 bits.

Answer 2

J'avais des problèmes pour installer lxml sur mon système avec urllib. Je ne me souviens pas pourquoi mais lxml n'était pas disponible pour python 3.5, urllib lui-même n'est pas disponible mais à la place il est disponible comme urllib.requests et un autre paquet dont je ne me souviens pas. Pour moi, la meilleure solution était d'installer anaconda à la place. Anaconda a juste autant de bibliothèques et cela fonctionne beaucoup à la place de python. Il a toute la bibliothèque d'url et une compréhension de plusieurs autres bibliothèques.
