Installing lxml module in python

while running a python script, I got this error

  from lxml import etree
ImportError: No module named lxml

now I tried to install lxml

sudo easy_install lmxl

but it gives me the following error

Building lxml version 2.3.beta1.
NOTE: Trying to build without Cython, pre-generated 'src/lxml/lxml.etree.c' needs to be available.
ERROR: /bin/sh: xslt-config: not found

** make sure the development packages of libxml2 and libxslt are installed **

Using build configuration of libxslt

src/lxml/lxml.etree.c:4: fatal error: Python.h: No such file or directory
compilation terminated.
error: Setup script exited with error: command 'gcc' failed with exit status 1

Solution 1:

Just do:

sudo apt-get install python-lxml

For Python 2 (e.g., required by Inkscape):

sudo apt-get install python2-lxml

If you are planning to install from source, then albertov's answer will help. But unless there is a reason, don't, just install it from the repository.

Solution 2:

I solved it upgrading the lxml version with:

pip install --upgrade lxml
