pip lxml install segmentation fault

Question

Запуск Python 2.7.5 и OSX 10.8. Также работает Python в виртуальном env, созданный с помощью менеджера пакетов Anaconda. У меня XCode 4.6.3 с установленными инструментами командной строки.

Мессинг вокруг с scraperwiki например:

import scraperwiki 
html = scraperwiki.scrape('https://scraperwiki.com/hello_world.html') 
import lxml.cssselect 
import lxml.html 
root = lxml.html.fromstring(html) # turn our HTML into an lxml object 
tds = root.cssselect('td') # get all the <td> tags 
for td in tds: 
    print lxml.html.tostring(td) # the full HTML tag 
    print td.text    # just the text inside the HTML tag 

Попытка использовать lxml.cssselect поднимает эту ошибку:

/Users/mmoncrief/anaconda/envs/py27/lib/python2.7/site-packages/lxml/cssselect.py in <module>() 
    16  external_cssselect = __import__('cssselect') 
    17 except ImportError: 
---> 18  raise ImportError('cssselect seems not to be installed. ' 
    19      'See http://packages.python.org/cssselect/') 
    20 

ImportError: cssselect seems not to be installed. See http://packages.python.org/cssselect/ 

Используя IPython, я искал установленных модулей под LXML (набрав LXML.) И найти только lxml.etree и lxml.get_include: нет модуля cssselect.

Я пробовал обновлять lxml, используя pip install lxml --update. Это дает ответ:

Пробовал удалить LXML и переустановка с ПУМАМИ, и я получаю ошибку лязга и сегмы неисправности. Вот раздел fro pip.log:

Любая помощь очень ценится!

Answer 1

Примечание сообщение об ошибке:

ImportError: cssselect seems not to be installed. See http://packages.python.org/cssselect/

---

cssselect был перемещен, чтобы стать отдельным пакетом. Попробуйте установить его с

pip install cssselect 

Answer 2

Это работает для меня, вместо установки LXML через:

pip install lxml

попробовать:

$CPATH=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include/libxml2 pip install -U lxml
