Próbowałem:Jak mogę zainstalować zależności lxml na linuksie Amazon EC2?
sudo yum install libxml2-dev libxslt-dev python-dev
i mam:
Loaded plugins: priorities, update-motd, upgrade-helper
amzn-main/latest | 2.1 kB 00:00
amzn-updates/latest | 2.3 kB 00:00
No package libxml2-dev available.
No package libxslt-dev available.
No package python-dev available.
pip nie działało.
Dostałem paczkę takiego:
git clone --branch lxml-3.2.4 https://github.com/lxml/lxml
Potem próbowałem bez Cython ponieważ sudo python setup.py install dał mi RuntimeError: ERROR: Trying to build without Cython, but pre-generated 'src/lxml/lxml.etree.c' is not available
sudo python setup.py install --without-cython
Potem dostałem:
sudo python setup.py install --without-cython

To naprawdę mnie chce do upewnij się, że pakiet rozwojowy wiek libxml2 i libxslt są instalowane.
Jeśli mogę to zrobić, mam nadzieję, że zadziała. Jakieś pomysły? Dzięki! Wygląda na to, że ludzie mają do tego podobne problemy, ale większość z nich dotyczy innych systemów.
UPDATE: podstawie sugestii vor za użyłem rozszerzenie -devel i że pracował zainstalować zależności.
sudo yum install libxml2-devel libxslt-devel python-devel
Niestety otrzymuję to:
$sudo python setup.py install --without-cython

jeśli zagłosujesz na zakończenie, ponieważ pytanie nie jest związane z programowaniem, nie ma problemu, ale możesz na nie odpowiedzieć, abym mógł go zaprogramować. także, czy kompilacja i zarządzanie pakietami nie są związane z programowaniem? – user391339
