pylint and astroid AttributeError: 'Module' object has no attribute 'col_offset'

[AndreasLuckert]

As I'd already asked on StackOverFlow, versions 2.9.0 and 2.9.3 seem to have this bug.

A workaround is to downgrade pylint to version 2.8.3, which still works.

EDIT:

I've just updated the OP with all python-packages involved in this testing environment, as well listing some attempts which did not work out to solve the problem.

Do you have an hint about the code that provoked the crash ? I'd want to add a regression test if possible (and also possibly do more than just avoid the crash and do the right thing). Ideally it would be a python file that would crash pylint with pylint a.py but simply the code around the problem could help too.

I'm afraid this is not possible at the moment to provide such information.
I'm working in a dev team on a complex project of a multi-national company involving highly confidential data.
Also, the code is built in a quite intricate and nested manner.

Let's hope that you will the issue, or other people experience similar problems and will be able to provide a full-working example code.

Ok, thank you for providing as much details as you can 😄 Blind fix it is then :) Could you maybe tell me if there is still a crash when installing astroid via : pip install git+git://github.com/PyCQA/astroid.git@c37b6fd47b62486fd6cbe77b913b568b809f1a6d#egg=astroid, please ?

[AndreasLuckert]

Thanks a lot for this hint!

Indeed, the combination

pip install pylint==2.9.3
pip install git+git://github.com/PyCQA/astroid.git@c37b6fd47b62486fd6cbe77b913b568b809f1a6d#egg=astroid

worked out without a failure (the entire AWS CodePipeline process testing and building the packages).

The dev team on my side decided that we're going to keep on using pylint==2.8.3 for this time being until there is a new official/stable version of pylint and astroid respectively.
Please let me know as soon as this is the case, so that we can update our build-scripts accordingly.
