Please copy the content of the stack trace into the issue description. Maintainers are not likely to download random files from the internet because of the apparent security risks 😄

[Pierre-Sassoulas]

Thank you for opening the issue :) Don't worry, I included the stacktrace in the issue.

@jacobtylerwalls Are you able to reproduce this?

I can't:

❯ cat test.py
import aiohttp

s = aiohttp.ClientSession()
❯ pylint --version
pylint 3.0.0b1
astroid 2.16.0dev0
Python 3.11.0b3 (main, Jun 12 2022, 16:13:11) [Clang 13.0.0 (clang-1300.0.29.30)]
❯ pylint test.py

--------------------------------------------------------------------
Your code has been rated at 10.00/10 (previous run: 10.00/10, +0.00)

[jacobtylerwalls]

No, I can't. But the stack trace looks like something important to fix, somewhere downstream of the namedtuple/enum brain an Uninferable got attached to the .args of an Arguments node, which shouldn't have happened. We could move this to astroid, I guess.

[DanielNoord]

Yeah, although that might also be a downstream package breaking something. Without an actual reproducer this will just stay open indefinitely..

Hello Folks,

It turns out this issue is due to using the embeded python installation (due to some restrictive admin policy on the server I'm using)

A regular installation of python does not generate this issue.

Here is a script I used to reproduce the issue with a fresh installation of python.

# expects 7zip installed at ${env:ProgramFiles}\7-Zip\7z.exe
#
# Download python embeded version 
# unzip it
# rename pythonXXX._pth to pythonXXX.pth
# get pip
# pip install virtualenv
# create virtal env
# activate virtualenv
# pip install aiohttp pylint
# create the test.py file
# lint the test.py
$version = "3.11.2"
$shortversion = "311"
$pythonurl = "https://www.python.org/ftp/python/$version/python-$version-embed-amd64.zip"
$zipfile = "$env:USERPROFILE\Downloads\python-$version-embed-amd64.zip"
$pythondir = "$env:USERPROFILE\Python"
$getpipurl = "https://bootstrap.pypa.io/get-pip.py"
Invoke-WebRequest -Uri $pythonurl -Outfile $zipfile
New-item -itemtype directory -path $pythondir
& ${env:ProgramFiles}\7-Zip\7z.exe x $zipfile "-o$($pythondir)"
Rename-Item -Path "$pythondir\python$shortversion._pth" -NewName "$pythondir\python$shortversion.pth"
Invoke-WebRequest -Uri $getpipurl -Outfile  $pythondir\get-pip.py
$env:Path = $pythondir + $env:Path
python $pythondir\get-pip.py
$env:Path = "$pythondir\Scripts" + $env:Path
pip install virtualenv
cd $env:USERPROFILE
virtualenv testenv
testenv\Scripts\activate
pip install aiohttp pylint
#update all packages
pip --disable-pip-version-check list --outdated --format=json | python -c "import json, sys; print('\n'.join([x['name'] for x in json.load(sys.stdin)]))"
New-item -itemtype directory -path "testenv\src"
New-Item -ItemType File -path "testenv\src\test.py"
Add-Content -Path "testenv\src\test.py" -Value "import aiohttp`r`n`r`na = aiohttp.ClientSession()"
# see if the lint crashes
pylint "testenv\src\test.py"

Replace the embeded python with regular python and the pylint works fine.

Is embeded python expected to work for this?
My solution is to further encourage our admins to install python properly on this server o remove the restriction on running msiexec.
