src/lxml/etree_defs.h: 9: 31: błąd krytyczny: libxml/xmlversion.h: Nie ma takiego pliku lub katalogu

Question

1. Używam następujący COMAND do instalacji pakietów w tym pliku " pip install -r requirements.txt --download-cache=~/tmp/pip-cache".

2. requirement.txt zawiera pacakages jak

# Data formats 
# ------------ 
PIL==1.1.7 # 

html5lib==0.90 
httplib2==0.7.4 
lxml==2.3.1 

# Documentation 
# ------------- 
Sphinx==1.1 
docutils==0.8.1 

# Testing 
# ------- 
behave==1.1.0 
dingus==0.3.2 
django-testscenarios==0.7.2 
mechanize==0.2.5 
mock==0.7.2 
testscenarios==0.2 
testtools==0.9.14 
wsgi_intercept==0.5.1 

gdy nadchodzi do zainstalowania "lxml" pakiety otrzymuję następujący eror

Requirement already satisfied (use --upgrade to upgrade): django-testproject>=0.1.1 in /usr/lib/python2.7/site-packages/django_testproject-0.1.1-py2.7.egg (from django-testscenarios==0.7.2->-r requirements.txt (line 33))

Czy ktoś może sprawdzić i prowadź mnie jaki byłby problem i dlaczego? Brak jakiegokolwiek pakietu do zainstalowania.

Answer 1

Install libxslt-devel & libxml2-devel używając

sudo apt-get install libxml2-dev libxslt1-dev 

Po zainstalowaniu się powyższej jeden

Answer 2

1. Install Cython użyciu

   easy_install Cython

2. Po zakończeniu Cython zainstalować libxslt-devel & libxml2-devel używając

   yum install libxslt-devel libxml2-devel

ten pracował dla mnie .

Answer 3

bez prawa sudo można zainstalować lxml z:

STATIC_DEPS=true pip install lxml 

Jak wspomniano lxml documentation

Answer 4

Wybrana odpowiedź r ma rację, ale chciałem tylko dodać, że ci, którzy używają Fedory: libxslt1 nazywa się libxslt podczas korzystania z dnf. Tak więc polecenie brzmi:

sudo dnf install libxml2-devel libxslt-devel 

devel dla DNF jest taka sama jak dev dla apt-get.
