Qualcuno può controllare e mi guida quale sarebbe il problema e perché? Qualsiasi pacchetto mancante per l'installazione.

Installare libxslt-devel & libxml2-devel usando

sudo apt-get install libxml2-dev libxslt1-dev

Dopo l'installazione seguire la sopra uno

Avviso per utenti di Ubuntu 13.04: se hai libxml2 già installato e aggiornato alla versione 2.9.0 + dfsg1-4ubuntu4.3 devi eseguire il downgrade a 2.9.0 + dfsg1-4ubuntu4.1 digitando il comando sudo apt-get install libxml2 = 2.9.0 + dfsg1-4ubuntu4.1 altrimenti il libxml2-dev non sarà installato a causa della dipendenza della versione. –

Qual è la differenza tra libxml2 e libxml? Grazie! –

@ Honghe.Wu qui puoi trovare i dettagli della differenza: http://xmlsoft.org/FAQ.html. In breve, andare per libxml2 – kmonsoor

Installare Cython utilizzando

easy_install Cython
Dopo il completamento della Cython, installare libxslt-devel & libxml2-devel usando

yum install libxslt-devel libxml2-devel

Questo ha funzionato per me .

questo è in realtà la risposta corretta (uso sudo apt-get Debian/Ubuntu) – roshan

@roshan: a destra, sudo apt-get install libxml2-dev libxslt1-dev –

per amazon Linux, 'sudo yum install libxml2- libxslt-devel devell' risolto per me, thx – Cmag

senza diritti di sudo è possibile installare lxml con:

STATIC_DEPS=true pip install lxml

Come accennato nella lxml documentation

La risposta selezionata è giusto ma volevo solo aggiungere per coloro che usano Fedora: libxslt1 si chiama libxslt quando si usa dnf. Quindi il comando è:

sudo dnf install libxml2-devel libxslt-devel

devel per DNF è la stessa dev per apt-get.
