Cannot install on ubuntu 22.04

[aleksejs-fomins]

I have followed the instructions to install pdfarranger from source on Ubuntu 22.04, Python 3.10.9

When I run

pip3 install --user --upgrade https://github.com/pdfarranger/pdfarranger/zipball/main
Collecting https://github.com/pdfarranger/pdfarranger/zipball/main

The installation procedure crashes with

  × Running setup.py install for pdfarranger did not run successfully.

Ok, apparently it was sufficient to run

sudo apt install gettext

However, that is not self-explanatory from the installation instructions on the main page.

Now, I have another problem. How do I actually run the code??

I have attempted to run it using python3 -m pdfarranger, that crashed with

ModuleNotFoundError: No module named 'gi'

I proceeded to do the following

sudo apt install libcairo2-dev libxt-dev libgirepository1.0-dev
pip install pycairo PyGObject

Now when I run python3 -m pdfarranger I get

'xkbcommon: ERROR: failed to add default include path /opt/anaconda3/share/X11/xkb'

And the program crashes with a segmentation fault. What am I doing wrong?

ModuleNotFoundError: No module named 'gi'

It's provided by python3-gi that you should have installed if you followed the README.

• See https://github.com/pdfarranger/pdfarranger#install-from-source (Debian based distribution)
• Yes gettext is missing. Thanks I'll add it.
• Mixing pip, conda and apt will give you indigestion. Uninstall pycairo, PyGObject, ensure you have no conda stuff in your environment and follow the README.
• If you use virtualenv or kind of do not forget --system-site-packages
• If you want to install with conda, you'll be on your own, because to my knowledge this has never been done (but if you manage to do it, share it!).

I see, indeed the problem was likely caused by using anaconda python by default. I'm sorry, it was not obvious to me that it was not ok to use anaconda-based python. I did indeed follow the readme before and installed python3-gi, but it was not visible to the anaconda python for whatever reason.
