Quelqu'un peut-il vérifier et me guider quel serait le problème et pourquoi? Tout paquet manquant à installer.

sudo ln -s libxml2/libxml libxml
.Installez Cython en utilisant
easy_install Cython
Une fois cython terminé, installez libxslt-devel & libxml2-devel en utilisant
yum install libxslt-devel libxml2-devel
Cela a fonctionné pour moi.
la source
sudo yum install libxslt-devel libxml2-devell
résolu pour moi,-dev
pour les paquets sur Raspbian. L'installation de cython a été délicate ... J'ai fini par devoir l'utilisersudo pip3 install Cython --install-option="--no-cython-compile"
pour qu'il fonctionne correctement.sudo pip3 install Cython
seul s'est écrasé eteasy_install3
n'a rien faitLa réponse choisie est correcte mais je voulais juste ajouter pour ceux qui utilisent Fedora:
libxslt1
est appeléelibxslt
lors de l'utilisation de dnf. La commande est donc:devel
pour dnf est le même quedev
pour apt-get.la source
sans droits sudo, vous pouvez installer lxml avec:
Comme mentionné dans la documentation lxml
la source
La réponse certifiée fonctionne parfaitement. Mais il suffit d'ajouter la commande d'installation pour alpine pour installer libxslt-devel & libxml2-devel
la source
--update
n'est généralement pas nécessaire.
