Install lxml on ubuntu 13.04 for python 3.3 Eclipse

Question

I have tried all of the following:

apt-get install python-lxml
apt-get install libxml2-dev libxslt1-dev
pip install lxml (gives me a compile error, no pyconfig.h)
easy_install lxml

Eclipse still does not recognize it when I try to import:

from lxml import etree

Please help.

Answer 1

Update your PYTHONPATH in Eclipse, go to Preferences > PyDev > Interpreters - Python Then update your paths to lxml package. I suggest you to reload your interpreter (first delete it, and next add it again) it will load all packages and PyDev will recognized lxml

Answer 2

Are you sure your script when you tried importing and were successful is running with the Python 2.x interpreter or whether it's using the Python 3.x interpreter? I suspect that python-lxml is only installing a Python 2.x version of lxml . Try python3-lxml .

Alternatively, if you wish to install using pip , your pip install of lxml 's error points to the lack of a pyconfig.h file which can be solved by sudo apt-get install python3-dev in your case (note that it's the python3-dev not python-dev , which only installs the required dev files for Python 2.x).

Answer 3

Try adding lxml to the Forced Builtins found within Preferences: PyDev -> Interpreters -> Python Interpreter, then select the Forced Builtin tab. It fixed it for me.
