'No name 'QtWidgets' in module 'PyQt5' and 'Unable to import 'PyQt5.QtWidgets' errors in vscode

[KikeSenpai]

Hello I am following the suggestion in the link below, about posting new issues for specifics modules in this case PyQt5
#1524 (comment)

Steps to reproduce

I imported the following classes from PyQt5 in order to build a Message Box:

from PyQt5.QtGui import QFont
from PyQt5.QtWidgets import (
    QApplication, QWidget, QLabel, QMessageBox, QLineEdit, QPushButton
)

Also I have the following setting in my settings.json:

"python.linting.pylintArgs": [
        "--extension-pkg-whitelist=PyQt5",
    ]

Thanks to this some error messages stopped showing but I still get the following errors in the problems tabs of vscode:

Current behavior

'No name 'QtWidgets' in module 'PyQt5'
'Unable to import 'PyQt5.QtWidgets'
'No name 'QtGui' in module 'PyQt5'
'Unable to import 'PyQt5.QtGui'

Expected behavior

No errors of this kind

pylint --version output

pylint 2.5.3 with Python 3.7.3 using the anaconda distributor

I can't reproduce this issue. Are you sure that the message is coming from pylint and not PyLance or some other part of vscode?
What versions of astroid and PyQt5 do you have?

I found the same problem. This problema was solved just with a Virtualenv.

Had the same problem with PySide6 on Linux. Problem seems to have been that system dependencies were not installed. sudo apt-get -y install xorg libxkbcommon0 helped.

I had this exact issue migrating to PyQt6, except it was manifesting in my linting github workflows. Your solution worked but Installing xorg and it's dependencies slows the workflow down significantly so I investigated and discovered you could run sudo apt-get -y install libgl1 libegl1 within that context and speed things up quite a bit.
