escaping - Visual Studio, install extension pylint failing with: AttributeError: 'HTMLParser' object has no attribute unescape

Question

Not possible to install some Extensions, like pylint or rope, ending always with

AttributeError: 'HTMLParser' object has no attribute 'unescape'

Plattform Context:

$ lsb_release -a

Distributor ID: Ubuntu
Description:    Ubuntu 18.04.5 LTS
Release:    18.04
Codename:   bionic

$ python --version

Python 3.8.3

$ code #visual studio

1.53.0
8490d3dde47c57ba65ec40dd192d014fd2113496
x64

While using visual studio 'popUp' hint option to install i.e. pylint, in terminal initiated comand says:

$ /home/harry/.vscode/extensions/ms-python.python-2021.1.502429796/pythonFiles/pyvsc-run-isolated.py  pip install -U pylint --user

starting well, but terminating with exception ("no attribute"):

harry@harry-ThinkPad-X220:~/.../MICROSERVICES$ /usr/bin/python /home/harry/.vscoy pip install -U pylint --user-2021.1.502429796/pythonFiles/pyvsc-run-isolated.py

Answer 1

VS was embedded in Python 3.9 and dependencies. After switch to Python 3.8.3, problem is gone, lint installed and working as expected.
