It fails using pylint version 2.9.0
and 2.9.3
. With version 2.8.3 it still works though.

EDIT on different attempts producing the same error:
pylint=2.9.3
astroid
and pylint
(latest versions, no version specification)astroid
and pylint
and upgrade astroid
to latest version during build-process (in AWS test-buildspec.yml) via pip install --upgrade astroid
(suggested here)Thanks to the work of @Pierre.Sassoulas this issue has been resolved (see here).
After having proven that the following combination of pylint
- and astroid
- versions worked well together without producing the OP-error, new commits have been made to the GitHub-project to fix the problem:
pip install pylint==2.9.3
pip install git+git://github.com/PyCQA/astroid.git@c37b6fd47b62486fd6cbe77b913b568b809f1a6d#egg=astroid
From here going forward, the issue should not occur again installing the latest version of pylint combined with astroid. Yet, if the issue returns, I'll let you know here.
