Installing lxml module in python

Question

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

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.

If you're using a virtual environment this is not the right answer. – AlexLordThorsen Aug 12 '15 at 19:46

I solved it upgrading the lxml version with:

pip install --upgrade lxml

You need to install Python's header files (python-dev package in debian/ubuntu) to compile lxml. As well as libxml2, libxslt, libxml2-dev, and libxslt-dev:

apt-get install python-dev libxml2 libxml2-dev libxslt-dev

and libxml2-dev and libxslt-dev. – Lennart Regebro Jan 04 '11 at 21:00

**libxslt** does not seem to be required (it was not for me, at least). Therefore, `apt-get install python-dev libxml2 libxml2-dev libxslt-dev` should be enough – Mathieu Feb 03 '13 at 08:04
I had to do this to install WeasyPrint, their `apt-get` instructions for Debian 7 alone didn't work. – cnst Feb 26 '14 at 15:32

**libxslt** was essential for me, lxml setup wouldn't go through without it. – axil Dec 30 '15 at 01:38

If you're running python3, you'll have to do:

pip3 install lxml

This is what worked for me! I was using the python3 and installing libraries for a previous version of python via `pip`. For `python3`, we should use `pip3`. – Victor Mar 08 '20 at 04:36

For RHEL/CentOS, run "python --version" command to find out Python version. E.g. below:

$ python --version 
  Python 2.7.12

Now run "sudo yum search lxml" to find out python*-lxml package.

$ sudo yum search lxml
Failed to set locale, defaulting to C
Loaded plugins: priorities, update-motd, upgrade-helper
1014 packages excluded due to repository priority protections
============================================================================================================= N/S matched: lxml =============================================================================================================
python26-lxml-docs.noarch : Documentation for python-lxml
python27-lxml-docs.noarch : Documentation for python-lxml
python26-lxml.x86_64 : ElementTree-like Python bindings for libxml2 and libxslt
python27-lxml.x86_64 : ElementTree-like Python bindings for libxml2 and libxslt

Now you can choose package as per your Python version and run command like below:

$ sudo yum install python27-lxml.x86_64

I am on Windows. Any solutions? – Paul Nov 22 '18 at 23:18 — Paul, Nov 22 '18 at 23:18
use "python2.7.exe -m pip install --upgrade lxml" – Oni Mar 05 '20 at 11:08 — Oni, Mar 05 '20 at 11:08

If you are encountering this issue on an Alpine based image try this :

apk add --update --no-cache g++ gcc libxml2-dev libxslt-dev python-dev libffi-dev openssl-dev make

// pip install -r requirements.txt
