Once I kind $ easy_install lxml I acquire:
Looking for lxml Speechmaking http://pypi.python.org/elemental/lxml/ Speechmaking http://codespeak.nett/lxml Champion lucifer: lxml 2.three Downloading http://lxml.de/records-data/lxml-2.three.tgz Processing lxml-2.three.tgz Moving lxml-2.three/setup.py -q bdist_egg --dist-dir /tmp/easy_install-7UdQOZ/lxml-2.three/ovum-dist-tmp-GacQGy Gathering lxml interpretation 2.three. Gathering with out Cython. Mistake: /bin/sh: xslt-config: not recovered ** brand certain the improvement packages of libxml2 and libxslt are put in ** Utilizing physique configuration of libxslt Successful record included from src/lxml/lxml.etree.c:227:zero: src/lxml/etree_defs.h:9:31: deadly mistake: libxml/xmlversion.h: Nary specified record oregon listing compilation terminated.
It appears that libxslt oregon libxml2 is not put in. I’ve tried pursuing the directions astatine http://www.techsww.com/tutorials/libraries/libxslt/set up/installing_libxslt_on_ubuntu_linux.php and http://www.techsww.com/tutorials/libraries/libxml/set up/installing_libxml_on_ubuntu_linux.php with nary occurrence.
If I attempt wget ftp://xmlsoft.org/libxml2/libxml2-sources-2.6.27.tar.gz I acquire
<palmy transportation information> ==> SYST ... finished. ==> PWD ... completed. ==> Kind I ... completed. ==> CWD (1) /libxml2 ... performed. ==> Dimension libxml2-sources-2.6.27.tar.gz ... completed. ==> PASV ... achieved. ==> RETR libxml2-sources-2.6.27.tar.gz ...

If I attempt the another archetypal, I’ll acquire to ./configure --prefix=/usr/section/libxslt --with-libxml-prefix=/usr/section/libxml2 and that volition neglect yet with:
checking for libxml libraries >= 2.6.27... configure: mistake: May not discovery libxml2 anyplace, cheque ftp://xmlsoft.org/.
I’ve tried some variations 2.6.27 and 2.6.29 of libxml2 with nary quality.
Leaving nary chromatic unturned, I person efficiently finished sudo apt-acquire instal libxml2-dev, however this modifications thing.
Since you’re connected Ubuntu, don’t fuss with these origin packages. Conscionable instal these improvement packages utilizing apt-acquire.
apt-acquire instal libxml2-dev libxslt1-dev python-dev
If you’re blessed with a perchance older interpretation of lxml altogether although, you might attempt
apt-acquire instal python-lxml
