It is not in the repos?!
Should I add a repo? how to?

UPDATE:

[limo@limo ~]$  pip install coloredlogs

you should install pip, if don’t available on your system.

yay -S python-pip

and run the command

sudo pip install jinja2

that installs jinja2

For reference:
Once you’ve overcome your problems installing ocrmypdf and tesseract-data-ara (normally yay -S ocrmypdf tesseract-data-ara --needed should suffice), simply run

ocrmypdf --output-type pdf -s -l ara input.pdf output.pdf

to attach the arabic ocr data to the newly created output.pdf.
Make sure the input.pdf has a high enough resolution; else your ocr results may be underwhelming.

To check which languages tesseract can access, run
tesseract --list-langs

If you need other languages, see here; install with sudo pacman -S <package-name>

Thank you @2000
Amazing and wonderful community as usual.
BUT I hope I can do without creating a new file!
Would giving the target file same name as source do?

I already did

try it with sudo, you need root permissions

sudo pip install jinja2

limotux · July 20, 2022, 3:57pm

Saying already satisfied!???
My system has gone bananas!?

pycrk · July 20, 2022, 4:00pm

if you look in the folder

/usr/lib/python3.10/site-packages

do you find the jinja2 folder there?

dalto · July 20, 2022, 4:01pm

Please stop. This is horrific advice.

Never, ever use sudo pip on an Arch based system

This is a direct path to broken updates.

pycrk · July 20, 2022, 4:01pm

i tried the commands by me, my output is different and jinja2 folder is available:

Yes,

ocrmypdf --output-type pdf -s -l ara input.pdf input.pdf

would overwrite the original pdf.

dalto · July 20, 2022, 4:03pm

Are we sure that jinja2 being missing is even the issue?

I don’t have that installed and my build went fine.

limotux · July 20, 2022, 4:04pm

Ooooops! I already did!
Can I revert back?

dalto · July 20, 2022, 4:05pm

In your case, it looks like it failed to do anything. Should be OK.

dalto · July 20, 2022, 4:05pm

Can we see the output of pacman -Q | grep -i jinja

limotux · July 20, 2022, 4:07pm

Yes, I have a few as follows, I tried lots of things:

jinja2
Jinja2-3.1.2-py3.10.egg-info
jinja2_time
jinja2_time-0.2.0-py3.10.egg-info

2000 · July 20, 2022, 4:08pm

It’s probably too late for you now, but for future refererence:
It’s not recommended to use pip to install system-wide packages! Use your package manager (pacman) instead.

I’d recommend reading up on Virtual environments to create a self-contained Python environment in which you can install whatever you want with pip, without it conflicting with your system down the road.

For example:

sudo pacman -S python-virtualenv
virtualenv path/to/my_virtenv
source path/to/my_virtenv/bin/activate

would leave you in your my_virtenv environment. Now, your Python interpreter will use packages from that environment, instead of your system-wide Python install. As long as you remain in this environment you can install whatever you want with pip, it’s not going to conflict with your system.

To exit the environment, just run the command deactivate. If you want to get rid of the environment completely, just delete the folder my_virtenv.

[Edit] Dalto beat me to it.

limotux · July 20, 2022, 4:09pm

[limo@limo ~]$ pacman -Q | grep -i jinja
python-jinja 1:3.1.2-2
python-jinja-time 0.2.0-7
[limo@limo ~]$

dalto · July 20, 2022, 4:11pm

What does pacman -Qo /usr/lib/python3.10/site-packages/jinja2 show?

limotux · July 20, 2022, 4:13pm

But he said

Hopefully it is still OK.
