• thinking it's the version conflict between each modules after I had updated all module version with command line: auto-review, but have no ideal how to check the conflict version since I'm fresh in python.
• win 10
• pytest=6.2.4

Hi @aalouie,

Please post the full output and the command you're trying to execute.

Hi @aalouie,

Please post the full output and the command you're trying to execute.

Now it is displayed.
Thanks for replay @nicoddemus

at first glance this looks like a broken python where argparse is missing callback actions
we need more details on the python used and the packages added to it

[RonnyPfannschmidt]

i took the liberty to add the tripple quotes for code around your traceback so its better readable

[RonnyPfannschmidt]

@aalouie i believe we require a list of the pytest plugins, pytest itself doesn't use the feature, i suspect legacy code may be involved and/or a broken plugin

[RonnyPfannschmidt]

@aalouie for more context - a very long while ago pytest used optparse instead of argparse

optparse has callback/callback_* arguments, argparse has action/type

[aalouie]

So, how should I do to provide this list for you?

Required-by: pytest-xdist, pytest-twisted, pytest-timeout, pytest-rerunfailures, pytest-pep8, pytest-ordering, pytest-metadata, pytest-instafail, pytest-html, pytest-for ked, pytest-flakes, pytest-django, pytest-cov, pytest-cache, pytest-bdd, pytest-asyncio

Do you mean this?

Do you have any idea to fix this? or to re-install python?
Since I have just repaired it by re-running python-3.9.6-amd64.exe, sadly doesn't work.

[RonnyPfannschmidt]

my next recommendation is to grep your site packages for all files with a pytest_addoption, and then find all of those that pass a "callback" value as action - that will find the breaker

Im using win10 64x, with Pycharm
Does it works with grep?

[RonnyPfannschmidt]

i have no idea how to "grep" on windows

on linux i'd install "silver searcher" and run ag "pytest_addoption" "c:\programdata\anaconda3\lib\site-packages" as a starting point
