Termux-app: Install python lxml

[nico202]

Hi, I'd like to install lxml.
I installed python2, and pip2 works for many packages, but not for lxml (pyconfig.h not found)
Anybody had success installing it?
Thanks :)

[fornwall]

Hi, pyconfig.h can be installed from the python2-dev package! Does installing lxml work for you after that?

[nico202]

installed the package, now fails including libxml/xmlversion.h
thanks
EDIT:
installing libxml2-dev, fails same way

[fornwall]

I reproduced the problem:

In file included from src/lxml/lxml.etree.c:239:0:
/data/data/com.termux/files/usr/tmp/pip-build-Vw5Hjr/lxml/src/lxml/includes/etree_defs.h:14:31: fatal error: libxml/xmlversion.h: No such file or directory
#include "libxml/xmlversion.h"

The file $PREFIX/include/libxml2/libxml/xmlversion.h exists after installing libxml2-dev, but is not found since -I$PREFIX/include/libxml2 is not used when compiling for some reason...

[fornwall]

Hi, the issue was that the libxml2-dev package lacked the xml2-config utility which lxml needs to build.

This has now been fixed, run apt update && apt upgrade and try to install lxml again.

Re-open the issue if it still doesn't work for you!

The problem seems to be unsolved.

Here's what I got.

[fornwall]

@Jim-Zenn Have you installed libxml2-dev with apt install libxml2-dev?

[Jim-Zenn]

Yes, I have. Can you reproduce this issue?

[Jim-Zenn]

It seems I succeeded to install after installing libxml2-utils, thanks!

[rafi16jan]

hey @fornwall I still got this issue even though I already install libxml2 libxml2-dev and libxml2-utils, how can I found a workaround?

[Grimler91]

@rafi16jan What error do you get?

[rafi16jan]

@Grimler91 I already got a workaround, I install libxslt1 and it worked

[Demigoddd]

@Grimler91 How did you install libxslt1 ?

[Grimler91]

@Deathlive apt search xslt shows me the packages libxslt and libxslt-dev so those are the ones you're after

[pigeonflight]

After install libxml2-dev, libxml2-utils and libxslt

pip2 install lxml

still fails with the following output:

unable to execute 'cc': No such file or directory
....
error: command 'i686-linux-clang' failed with exit status 1

[pigeonflight]

It seems I was missing 'clang'.

pkg install clang

did the trick, so I'm back on track. Now to go figure out how to cut and paste from termux.

[cy3erGh0sT]

I still have error installing lxml with ('Python.h' file not found).Anybody have any solution?.

I try again after installing python2-dev now fails including 'crypt.h'

thank you.

[xeffyr]

@cy3erGh0sT libcrypt-dev needed

[cy3erGh0sT]

Thank you very much.The problem has been fixed after installing libcrypt-dev.

$PREFIX/include/libxml2/libxml/xmlversion.h exists after installing libxml2-dev, but is not found since -I$PREFIX/include/libxml2 is not used when compiling for some reason...

[dpshelio]

This may help:

pip install --global-option=build_ext --global-option="-I$PREFIX/include/libxml2" lxml

Hey buddies, looks like there's too much mess (& dependencies) to figure out.
So, I just compiled it & uploaded the wheel file.
Now, you don't have to have the headache. Just install the wheel.
Wheels are in my repository :

[medram]

hey there,
I solved this problem using
pkg install clang
pkg install libxml2 libxslt
pip install cython
pip install lxml
have a good day :-)

[ajitjadhav28]

@Grimler91 I already got a workaround, I install libxslt1 and it worked

Working(python3):
apt install clang libxml2 libxslt
then install lxml by pip install lxml

[dyaus2613]

it solved my problem
I use these
pip install wheel
pkg install libxml2 libxslt

[sk8heidong]

ok
now ihave lxml
so exciting ~
